Type O.
One gene comes from the mother and one gene comes from the father. So therefore, the child would either be an A, B, or AB blood type but could not be a type O because the father wouldn't have one O gene to give.

I'll break it down for you so it is easier to see.
A man with Type AB blood got a gene from his Mom for A or B and a gene from his dad for the other, for this we'll just say Dad gave him A and Mom gave him B. This means that the ONLY genes he can pass on to his offspring is for Type A or Type B.
Type O blood is due to two recessive genes for that blood type. In order for that to occur, BOTH parents must have the gene, either by being Type O or being Type A or B with the O recessive.
Therefore, Type AB can only have an A or B type child.

O....the reason......
O blood type is OO genotype and required 1 O allele from each parent. O is also recessive and even if the other parent gives an O allele, the child will either be A or B
eg.
----A---------B
O--AO-----BO
O--AO------BO
Offspring will be 50% A or B in this case.....

Type O. His child can be type A, B, or AB.
