Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. CW 105.
Logic: First letter + 1 , Second letter + 1, Number + 4
B + 1 = C; C + 1 = D; D + 1 = E; E + 1 = F;
V + 1 = W; W + 1 = X; X + 1 = Y; Y + 1 = Z;
101 + 4 = 105; 105 + 4 = 109; 109 + 4 = 113; 113 + 4 = 117;
