To ensure the maximum cross-browser compatibility and consistent functionality, Web developers should:

Options

• ATest their pages in the most used release of each major Web browser.
• BTest their pages in the most common browsers, including the most used and latest releases.
• CTest their pages in only standards-compliant browsers, including the most used and latest releases.
• DTest their pages in the Web browser most commonly used by the site audience, including the most

• D

Explanation

Option B is correct because thorough cross-browser compatibility testing requires covering both the most used releases (to reach the majority of real users) and the latest releases (to ensure forward compatibility and catch regressions with new browser updates) across all major browsers.

Option A fails because testing only the most-used release ignores users on the latest versions, which often behave differently due to engine updates and new standards support. Option C is too restrictive - limiting tests to only "standards-compliant" browsers excludes legacy or partially-compliant browsers that a significant portion of users still run. Option D is incomplete; focusing only on the site's most common audience browser creates blind spots for users arriving from other browsers, and the answer choice is cut off, suggesting it lacks the breadth of B.

Memory tip: Think "Most + Latest = B is Greatest" - you need the most used (coverage) AND the latest (future-proofing) across common browsers, not just one browser or one type.
