If SUDDEN is coded as RVCEDO, then what will GROWTH be coded as?

Given: SUDDEN is coded as RVCEDO

Logic:  1st letter is decreasing by 1 and 2nd letter is decreasing by 1 alternatively. 

S - 1 = R , U + 1 = V,  D -1= C, D +1 = E , E -1 = D , N +1 = O

Similarly: GROWTH : 

 G - 1 = F,  R +1 = S, O -1 = N, W +1 = X , T -1 = S, H +1 = I  

Thus, correct option is (d).
