To determine the probability of the offspring's blood type, we can analyze the blood types of the parents based on their genotypes.

- The mother with type O blood has the genotype **OO**.
- The father with type AB blood has the genotype **AB**.

When they have children, the possible combinations of alleles are:

- From the mother (OO), the only allele she can pass is **O**.
- From the father (AB), he can pass either **A** or **B**.

Thus, the possible genotypes for the offspring are:
1. AO (which results in type A blood)
2. BO (which results in type B blood)

Since there are no combinations that result in type O blood (which requires the genotype OO), the probability that the offspring will have type O blood is **0%**.

So the correct answer is **0%**.
