We have been given the truth table for three variables p, q, and r. as shown below


p q r

A T T T

B T T F

C T F T

D T F F

E F T T

F F T F

G F F T

H F F F


Now we need to find Which statements are true for rows A and E for the following statements:

p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q


To find that we need to use table of P <-> Q as shown in picture.

We know that if both statements are true for P and Q then only P <-> Q will be true. So using that trick we see that only q<->r and r<->q are the final answer as shown in the attached picture.
