​In a certain code language, BRIDE is written as FVMHI. How will SINGLE be written as in that language? ​

Given: 

Logic: Each letter in the word is increasing by 4 positions in the alphabet.

B → F; B + 4 = F

R → V; R + 4 = V

I → M; I + 4 = M

D → H; D + 4 = H

E → I; E + 4 = I

Similarly, 

S → W; S + 4 = W

I → M; I + 4 = M

N → R; N + 4 = R

G → K; G + 4 = K

L → P; L + 4 = P

E → I; E + 4 = I

Therefore, SINGLE is written as WMRKPI in the code language.

Thus, the correct option is (c)
