In the following question, select the related letters from the given alternatives.
ABC : HGF : : XYZ : ?

Given: ABC : HGF : : XYZ : ?

Logic: 1st letter + 7 = 4th letter, 2nd letter + 5 = 5th letter and 3rd letter + 3 = 6th letter

For, ABC : HGF

A + 7 = H, B + 5 = G, C + 3 = F

Similarly,

XYZ : ?

X + 7 = E, Y + 5 = D, Z + 3 = C

So, XYZ : EDC

Thus, correct option is (d).
