Explanation
Testing with current and older versions of multiple browsers (C) ensures your pages work for the widest possible audience, since many users run outdated browsers and different browsers render HTML/CSS differently. Limiting to only current versions (A) ignores the significant portion of users who haven't updated, leaving them with broken experiences. Options B and D are wrong because they restrict testing to specific browsers (IE/Firefox or IE/Chrome), excluding others like Safari, Edge, Opera, and mobile browsers that have substantial market share. Real-world web pages must function across the entire browser ecosystem, not just two vendors.
Memory tip: Think "C = Complete coverage" - you need all browsers (not just two) across all versions (not just current) to truly validate cross-browser compatibility.

Fatima Z.Nov 24, 2025C is your answer, and here is the hook to nail it forever: think "COMB" - Current and Older, Multiple Browsers. You test with current AND older versions of MULTIPLE browsers because real users out in the wild are not all running the latest update, and different browsers render HTML and CSS in their own quirky ways, so skipping either dimension means your pages will break for someone visiting your site.
Renata O.Dec 4, 2025I honestly first picked A because testing across multiple browsers already felt thorough enough, but then I remembered that real users do not all update on the same schedule, so a site has to hold up in older versions too, not just whatever shipped last month. That is what makes C the right call, since you need both current and older versions of multiple browsers to cover the actual range of environments your visitors are using.
Orla P.Dec 9, 2025I almost marked B on this one because I had just been drilling browser-specific stuff all week and my brain went straight to the named browsers, but then I caught myself and remembered the question is really asking about coverage across versions, not brand names, so C was the only one that held up.
Prof. SaraDec 11, 2025That version-versus-vendor trap is exactly what the blueprint is testing in that domain objective, and the fastest way to immunize yourself against it is to ask one filter question before committing: "Is the question counting names or counting configurations?" because C always wins when configurations are the unit of measure.
Prof. SaraDec 14, 2025Honestly, my first instinct was to pick A, because in practice most of us focus on modern browsers and figure legacy support is a solved problem. But then I caught myself, because the question is asking about sound development practice, not just what's convenient today. The key word is "important," and the real-world reality is that a meaningful portion of your users are still running older browser versions, whether by choice, corporate policy, or hardware limitations, so testing only current versions leaves a gap that will bite you in production. Option C wins because it pairs the breadth of "multiple browsers" with the depth of "current and older versions," which is the complete picture the CIW blueprint expects you to carry into a professional web development context.
Dervla O.Dec 16, 2025My first instinct was A, because "current versions" felt sufficient and D and B both lock you into specific browsers, which you can eliminate fast for being too narrow. What flipped me to C was reading the stem a second time, specifically the word "important," which is a signal to think about real-world coverage, and older browser versions are absolutely still in circulation among end users, so testing only current versions leaves a gap the exam writers are specifically testing whether you recognize.
Prof. SaraDec 18, 2025Good catch on "important" as a scope trigger, and the B-and-D elimination was clean, but also note that any answer tied to a single vendor name is almost always a trap on these exams because standards-body objectives are written to be vendor-neutral, so you can often discard those before even reading the stem carefully.
