Binomial approximation problem, but it has non-integer boundaries, which is inconsistent. Be that as it may
mean is np=0.75*202=151.50.
Since the limits are symmetric around 151.50, the answer has to be b.
If you want to do the whole thing, np(1-p) is the variance 37.875, and sd is sqrt(V)=6.15
The interval has to be 12.30 on each side or 24.30 wide. This again is b.
