Correct choice: B

Explanation:

I. Total candidates interviewed by 3 panels = (15 x 3) = 45.

II. Let x candidates be interviewed by C.

Number of candidates interviewed by A = (x + 2).

Number of candidates interviewed by B = (x + 1).

∴ x + (x + 2) + (x + 1) = 45

⇒ 3x = 42

⇒ x = 14

Hence, the correct answer is (B).
