Explanation

Option A is correct because Python's re module provides regular expressions - a formal language of special characters and sequences (like \d, *, ^, $) that let you match, search, and validate string patterns with a single concise expression. Option B is wrong because this is a factual statement with no ambiguity: regular expressions are a well-established feature in Python's standard library, not an opinion or edge case. Since there are only two choices here, B is simply the negation of a true statement.

Memory tip: Think of a regular expression as a filter stencil - you describe the shape of what you're looking for, and Python checks whether a string fits through it. If you've ever used wildcards like *.txt in a file search, you've used the same concept, just with more power.
