What is the purpose of using comments to prevent execution in programming?
A). To increase code execution speed

How can developers ensure that comments used for preventing execution do not affect the code's functionality?
A). By using comments only at the end of the code block
B). By ensuring that comments are well-documented and provide clear explanations
C). By using multi-line comments for single-line comments, ensuring consistency
