Explanation

In Python, the # character marks everything to its right on that line as a comment, which Python's interpreter ignores entirely - this is the standard, built-in mechanism for annotating code for human readers. Option A is wrong because placing notes after the last line of code (separated by a blank line) is not valid Python syntax for comments - Python would try to interpret that text as code. Option C is wrong because parentheses are used for function calls, tuples, and grouping expressions, not for comments; text inside parentheses is treated as a string or expression. Option D is wrong for the same reason as A - plain text before your code without a # prefix is a syntax error unless it's a string literal. A helpful memory tip: think of # as the "hashtag for humans" - just like a hashtag labels content for a specific audience on social media, # labels a line of code as a note meant for people, not the interpreter.
