19. The logic of pumping lemma is an example of __________.

  • Option : D
  • Explanation :
    Pigeon-hole principle states that if there are n pigeons fly into m hole and n > m then atleast one hole must contain more then one pigeons. And logic of pumping lemma states that- finite state automaton can assume only a finite number of states and because there are infintely many input sequence, by the pigeon hole principle , there must be atleast one state to which the automata returns over and over again. So, option (D) is correct.
