Correct Answer

A

Explanation

To find 2*(3,4) using the binary operation *, we substitute p = 2 and q = (3,4) into the definition of the operation.Using the definition p*q = pq + p + q, we have:2*(3,4) = 2(3,4) + 2 + (3,4)Now, let's evaluate each term separately:2(3,4) = 2(3*4) + 2 + (3+4)= 2(12) + 2 + 7= 24 + 2 + 7= 33Therefore, 2*(3,4) = 33.
