Answer
Candidate B is selected as the winner using the Borda count method.
Work Step by Step
With the Borda count method, each candidate receives 1 point for each last place vote, 2 points for each second-to-last-place vote, and so on. The candidate with the most points is declared the winner.
We can find the total points for each candidate.
Candidate A:
3(1200) + 2(900 + 600) + 1(900) = 7500 points
Candidate B:
3(900 + 600) + 2(1200) + 1(900) = 7800 points
Candidate C:
3(900) + 2(900) + 1(1200 + 600) = 6300 points
Since Candidate B received the most points using the Borda count method, Candidate B is selected as the winner.
