Correct answer: A

Explanation of the pattern: 

The analogy follows a pattern where the first number in each pair is

n×(n+1), and the second number is (n+1)×(n+2)

First Pair (42 : 56):

42=6×7

56=7×8

Second Pair (110 : ?):

110=10×11

Following the pattern, the missing number should be

11×12

Calculation:

11×12=132
