Correct option is D
Logic: second number × (second number-1)= first number
42 : 7
7×(7-1)=7×6=42
and
110 : 11
11×(11-1)=11×10=110
Now, check options,
132 : ?
Check option (a) 13
13×(13-1)=13×12=156
So, its not correct.
Check option (b) 15
15×(15-1)=15×14=210
So, its not correct.
Check option (c) 17
17×(17-1)=17×16=272
So, its not correct.
Check option (d) 12
12×(12-1)=12×11=132
So, its correct.
Thus, correct option is (d).
