Is it possible for mother (O) and father (AB) to produce an offspring with AB blood type? I got a question wrong under the assumption that that kind of matching could happen through mutation.

I don't think it's possible because mother would have ii and father would have iaib. So the only combination you can get it iai or ibi which is A or B blood type.
I don't think you can assume mutations can happen unless the question somehow refers to it.
I would just recommend that you use the information provided by the question, assuming normal conditions. And if the question mentions a mutation that could lead to a different genotype than expected in the offspring, then you could make the assumption that you originally did.
