I had been asked this question in a job interview.

This interesting question is from Pumping Lemma for Regular Language in division Properties of Regular Languages of Automata Theory

Answer 1

Correct answer is (b) Pumping

The explanation is: The process of repeatation is called pumping and so, pumping is the process we perform before we check whether the pumped string belongs to L or not.
