Negation of the Boolean expression p ↔ q → p is

Options

  1. A~ p ∧ q
  2. Bp ∧ ~ q
  3. C~ p ∨ ~ q
  4. D~ p ∧ ~ q

Correct answer

D. ~ p ∧ ~ q

Step-by-step solution

To find ~ p ↔ q → p We know ~ p ↔ q ≡ p ∧ ~ q ∨ q ∧ ~ p So ~ p ↔ q → p ≡ p ∧ ~ q → p ∨ q → p ∧ ~ p Now p ∧ ~ q → p ≡ p ∧ q ∧ ~ p ≡ p ∧ ~ p ∧ q ≡ c and q → p ∧ ~ p ≡ ~ q ∨ p ∧ ~ p ≡ ~ p ∧ ~ q ∨ p ≡ ~ p ∧ ~ q ∨ ~ p ∧ p = ~ p ∧ ~ q Hence ~ p ↔ q → p ≡ c ∨ ~ p ∧ ~ q &#880
