Answer:B or C
Explanation:
The answer is either B or C because out of 240 votes, 150 votes (B) or 180 votes (C) would have the majority of the votes available, making for a sure win for the winner.
It could not be D because there cant be 320 votes out of 240
It "cant" be A because although there can be 60 out of 240 votes, assuming there are 2 candidates, 60 would be less than the number of votes the opposition would have thus the "winner" would not have "won"
This is answered assuming there are only 2 candidates. A more in-depth question would aide to answering the question better.
