One drawback to the Condorcet method of voting is that

a. The results are sensitive to the order of voting

b. The results are sensitive to irrelevant alternatives

c. There may not be a winner

d. It is possible that the winner is disliked by a majority of voters

c. There may not be a winner

Explanation:

The Condorcet method of voting is done by pairing the candidates together on the ballot paper. The candidate who has a majority vote emerges the winner.

It is a one round preferential voting system.

In this election, the setback is there may be no winner because the choice of the voters selecting from more than two candidates could be cyclic. It's very rare but possible for candidate having an opponent to defeat them in a two-candidate contest.
