Options

A. PY
B. PZ
C. YZ
D. ZA

Answer

A

Explanation

Divide the given alphabet series into groups of letters each :
(AJKTU) (BILSV) (CHMRW) (DGNQX) (EFO??)
Form the sequences as follows: First letter of consecutive groups = A, B, C, D, E
Second letter of consecutive groups = J, I, H, G, F
Third letter of consecutive groups = K, L, M, N, O
Fourth letter of consecutive groups = T, S, R, Q, ?
and fifth letter of consecutive groups= U, V, W, X, ?
So, Missing letters are P and Y.
