The answer is q↔r and r ↔q.
EXPLANATION
↔is a symbol for biconditional statements. Meaning, the statement is defined to be true whenever both parts have the same truth values.
In Row A, you can find both p and q, q and r, and p and r have the same truth values, which is T.
However, in Row E, only q and r, and r and q have the same truth values.
The question asks for both rows, so, you just need to find the common intersection between the two. Thus, the answer stands as it is.
