Consider the following problems. L(G) denotes the language generated by a grammar G. L(M) denotes the language accepted by a machine M. (I) For an unrestricted grammar G and a string w, whether wϵL(G) (II) Given a Turing machine M, whether L(M) is regular (III) Given two grammar G1 and G2, whether L(G1) = L(G2) (IV) Given an NFA N, whether there is a deterministic PDA P such that N and P accept the same language Which one of the following statement is correct?
  • a)
    Only I and II are undecidable
  • b)
    Only II is undecidable
  • c)
    Only II and IV are undecidable
  • d)
    Only I, II and III are undecidable
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider the following problems. L(G) denotes the language generated b...
I, II and III are undecidable, refer this:

Coming to IV, every regular language is Deterministic-CFL, which is a trivial property. Option (D) is Correct.
