Which notation denotes a multi-line comment?

• A. // comment
• B. /(asterisk symbol) comment (asterisksymbol)/
• C. -- comment
• D. /* comment */

Answer: (B)

A multi-line comment is marked by opening with /* and closing with /. Everything between these delimiters is ignored by the compiler, so you can spread the comment across several lines. This is different from // or --, which are single-line comments that end at the end of the line. The exact form is / comment */, which is why that notation is used to denote a comment block that can span multiple lines.
