percent. the probability that their offspring would also be a carrier

Both the parents are carriers of sickle cell anaemia. A carrier can be described as a person who carries a diseased causing allele but the allele is not functional in the body of the person due to the dominant allele suppressing its activity. Such kind of people might produce children actually having the disease.

In the above scenario, there is a 25% chance that the children born will be normal.

There is a 50 percent chance that the children born will be carriers, like the parents.

There is a 25% chance that the child born from these parents might have sickle cell anaemia.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
