Explanation:

Selecting a girl from section A and section B is 1/4 and 4/9 respectively.

Selecting a boy from section A and section B is 3/4 and 5/9 respectively.

Case 1: A girl from section A and a boy from section B.

P1 = (1/4) × (5/9) = 5/36

Case 2: A boy from section A and a girl from section B.

P2 = (3/4) × (4/9) = 12/36

Required probability = P1 + P2 =17/36

Hence, option (d).
