​In a certain code language, CARPENTER is written as AAPPCNREP. How will KITCHEN be written as in that language?​​

CARPENTER is written as AAPPCNREP in a certain code language

Logic: Decrease the value of alphabet letters at odd positions by 2 and keep letters at even positions unchanged.

C-2 = A, A=A, R-2= P, P= P, E-2 = C, N= N, T-2 = R, E= E, R-2 = P

K-2= I, I= I, T-2= R, C= C, H -2= F, E= E, N-2= L

IIRCFEL, is the correct answer 

Thus, correct option is (c) IIRCFEL
