Why is B zero order and why is C first order?

B is zero order because when the rates are equal to each other when finding the answer it results in log 1 which is 0. so anything divided by 0 is 0. Then, because you know that b is zero order, you also know that it is not include in the rate law. When you go to find the order of C, you do not have to account for any of the B values.

The concentration of B still changes though. Why is this not taken into account?

The concentration of B may change but the overall rate shown does not change so it technically gets multiplied by 1. Then that means B would be zero order since B^0 equals 1 so it does not need to be included in the rate law.
