(C):

Total number of votes polled = 83457
Votes polled in favour of one candidate = 49682
Let the number of votes polled in favour of other candidate be X.
Number of invalid votes = 2974
So, 83457 = 49682 + X + 2974
83457 = 52656 + X

X = 83457 – 52656
X = 30801
Therefore, the number of votes polled in favour of other candidate is 30801.
