Show answer & explanation

Correct answer: D

Write N = 4P in prime-power form: N = 2^2 × P^1

Total number of divisors is (2+1)(1+1) = 3 × 2 = 6.

Number of odd divisors (set the power of 2 to 0) = (1+1) = 2.

Number of even divisors = total − odd = 6 − 2 = 4.

The even divisors are: 2, 4, 2P, and 4P (including N = 4P).
