If p : The total prime numbers between 2 to 100 are 26 . q : Zero is a complex number. r : Least common multiple (L.C.M.) of 6 and 7 is 6 . Then which of the following is correct?

Options

  1. A(p q) r has truth value False.
  2. B( p q ) r has truth value True.
  3. C(p q) r has truth value False.
  4. D( p q ) ( q p ) has truth value True.

Correct answer

C. (p q) r has truth value False.

Step-by-step solution

The truth values of p , q and r are F , T and F respectively. Consider option (C) aligned & (p q) r & (F T) F & T F & F . aligned
