Select the pair that follows the same pattern as that followed by the two set of pairs given below. Both pairs follow the same pattern.
YAB−DFG
RTU−WYZ

Given: 

YAB−DFG
RTU−WYZ

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

For, YAB−DFG

Y + 5 = D, A + 5 = F, B + 5 = C

For, RTU−WYZ

R + 5 = W, T + 5 = Y, U + 5 = Z

Now, we check each options.

Option (a): WYZ−ADD (Not Follow)

W + 5 $$\neq$$ A, Y + 5 = D, Z + 5 $$\neq$$ D​

Option (b): ACD−FHI (Follow)​

A + 5 = F, C + 5 = H, D + 5 = I

Option (c): WXX−ACD (Not Follow)​

W + 5 $$\neq$$​ A, X + 5 = C, X + 5 $$\neq$$​ D

Option (d): WXX−BDE (Not Follow)​

W + 5 = B, X + 5 $$\neq$$​ D, X + 5 $$\neq$$​ E

Thus, correct option is (b).
