Explanation

The correct option is Z
By Decoding the given Sequence in the way A→1; B→2;....Z→26

A, D, H, M, S → 1,4,8,13,19

The difference between two successive numbers is increasing by '1' starting from with '3'

1+3=4

4+4=8

8+5=13

13+6=19

19+7=26

Hence according to decoded language, the next number is '26' i.e Z
