For the given Grammar
S->aA|bB
A->bC|aS
B->aC|bS
C->aB|bA
Construct DFA I am getting confused in understanding how to take the final state.

So is the question wrong cause it is supposed to check if grammar generates even number of a's or b's

Yes.
This is not the grammar generating even no. of a's and b's..it is not halting. :/

for any random string if the given grammar generate it,then we definitely can draw DFA,otherwise not.
and since the grammar doesnot have any terminating condition ,therefore,it is not possible.
