Consider the following three statements P: 11 is a prime number. Q: 7 is a factor of 176 . R : LCM of 3 and 7 is 21 . Then, the truth value of which one of the following statement is true?

Options

  1. AP ( Q R)
  2. B( P) ( Q R)
  3. C(P Q) ( R)
  4. D( P) (Q R)

Correct answer

A. P ( Q R)

Step-by-step solution

P: 11 is a prime number ( T )Q: 7 is a factor of 176( ~F )R : L.C.M of 3 and 7 is 21 (T) Now, P ( Q R) T ( T T ) T
