In a certain code language, HRMGL is written as DMGZD. How will NDCKR be written as in that language?

Given: 

HRMGL → DMGZD.

NDCKR → ?

Logic: Letters are decreasing by -4, -5, -6, -7, -8, in alphabetical order.

H - 4 = D, R - 5 = M, M - 6 = G, G - 7 = Z, L - 8 = D

Now, As the similarly: NDCKR → ? 

N - 4 = J, D - 5 = Y, C - 6 = W, K - 7 = D, R - 8 = J

So, NDCKR →  JYWDJ.​

Thus, the correct answer is: (B) JYWDJ.
