Correct option is A
Given :
12% did not vote
Votes polled = 88% of Total voters
10% of votes polled were invalid
Valid votes = 90% of 88% of Total voters
A received 56% of valid votes
B received 44% of valid votes
A defeated B by 4752 votes
Solution :
Let total valid votes = V
Difference of votes
(56% - 44%) of valid votes = 12% of valid votes
12% of V = 4752
V =39,600
Votes received by B
= 44% of 39,600
= = 17,424
