Correct option is C

A → D → I → P → ?
A + 3 = D
D + 5 = I
I + 7 = P
P + 9 = Y
Number pattern: 4, 9, 16, 25, ?
4, 9, 16, 25, ?
2², 3², 4², 5² → 6² = 36
Last letter pattern: C → G → M → U → ?
C + 4 = G
G + 6 = M
M + 8 = U
U + 10 = E
Thus, the missing term is Y36E.
Thus, the correct option is (c) Y36E.
