Open-ended comment designations such as -- to comment out a line are not supported.

Open-ended comment designations such as -- to comment out a line are not supported.

• A. Depends
• B. Not specified
• C. False
• D. True

Answer: (D)

Understanding which comment styles the environment recognizes is being tested. The statement here says that open-ended markers like -- to comment out a line are not supported. If the parser doesn’t treat -- as a comment delimiter, that portion of the line isn’t ignored and will be processed as code, leading to errors or unexpected behavior. So this assertion is true: that particular comment style isn’t supported in this context, and you’d need to use the environment’s supported comment syntax (such as // or /* ... */ or a template directive) to comment a line. The other options would imply the behavior is conditional, unspecified, or that the syntax is supported, which contradicts the given statement.
