A note in the source code of a computer program that helps explain the code to people who read it.

• A. Bug
• B. Whitespace
• C. Comment
• D. Hyperlink

Answer: (C)

In programming, a comment is a note added to the source code to explain what the code does, why it’s written a certain way, or how to use it. It’s for humans to read, not for the computer to execute, so the program ignores comments when it runs. That makes comments the best description of a “note in the source code that helps explain the code to people who read it.” A bug is an error in the code that causes incorrect behavior, whitespace is just formatting characters that help readability but don’t convey explanations, and a hyperlink is a web link, not a built-in way to document the code itself.
