How do you input comments in PowerShell?

• A. # for block
• B. <!-- -->
• C. //
• D. # or <# #> for block

Answer: (D)

PowerShell uses a hash symbol for single-line comments and a block comment delimiter for multi-line comments. A line starting with # is ignored by the interpreter, so you can annotate code or temporarily disable a line. For longer notes, wrap them in a block: start with <# and end with #>. This lets you comment out several lines at once without prefixing each line with #. Some other comment styles, like // or HTML-style <!-- -->, aren’t used in PowerShell, since those come from other languages. Example: # This is a single-line comment <# This is a block comment spanning multiple lines #>
