Explanation

Comments in code are annotations meant for human readers - they are ignored by browsers and serve no functional role in execution, making their primary purpose documentation and communication among developers (C). Option A is wrong because JavaScript is inserted via <script> tags, not comments. Option B is wrong because comments are invisible to site visitors - they only appear in the source code. Option D is wrong because HTML version is declared using a <!DOCTYPE> tag, not comments.

Memory tip: Think of comments as "sticky notes" left by one developer for another - they explain the why behind the code, never doing anything the browser acts on.
