What should come in place of the question mark (?) in the given series based on the English alphabetical order?
DDI, BBD, ZZY, XXT, ?

Given: DDI, BBD, ZZY, XXT, ?

Logic: 1st and 2nd letters - 2, 3rd letters - 5 

First letters: D, B, Z, X, 

D - 2 = B, B - 2 = Z, Z - 2 = X, X - 2 = V

Second letters: D, B, Z, X, 

D - 2 = B, B - 2 = Z, Z - 2 = X, X - 2 = V

Third letters: I, D, Y, T

I - 5 = D, D - 5 = Y, Y - 5 = T, T - 5 = O

So, the next term will be VVO.

Thus, the correct option is (b) VVO.
