Explanation
Option A is correct because Python identifiers can indeed be composed of three types of characters: letters (a–z, A–Z), digits (0–9), and underscores (_). Since the question presents only two choices (True/False), option B is the only distractor - it is wrong because it would imply identifiers have different or additional restrictions, which is not the case.
One important nuance to remember: while numbers are allowed within identifiers, they cannot appear as the first character - var1 is valid, but 1var is not. A helpful memory tip: think of a valid Python identifier like a proper name - it can contain numbers (like "R2D2"), but it can't start with one.
