Draw a punnet square and put the A and B alleles on one axis. Type O blood means that this person is homozygous for O (ie. has two O alleles). Put these alleles on the other axis.
A B
O AO BO
O AO BO
Remember that A and B are dominant to O, so only one answer is possible given your choices.

She could have A or B. She will receive an "O" allele from dad and either an "A" or "B" from mom. O is recessive and A and B are dominant.
So, the answer is A. A
