How is a generator different from a regular function?

The correct answer is Option B: A generator can yield multiple values.
Generators and regular functions in Python are different in how they operate. Regular functions use the return keyword to return a single result and terminate execution. In contrast, generators use the yield keyword to produce a sequence of values lazily. Generators can yield multiple values over successive calls to the next() function or through iteration, whereas regular functions return only once. This feature of generators enables them to efficiently handle large datasets or infinite sequences without consuming excessive memory.
