Answer:
B) $5,000
Explanation:
Bob and Sally can claim an American Opportunity (AO) credit for both of their children, Del and Owen.
Del's AO credit is $2,500 (100% of the initial $2,000 qualifying expenses and 25% of the next $2,000 qualifying expenses).
Owen's AO credit is the same as Del's, $2,500.
The total American Opportunity credit claimed is $5,000 ($2,500 + $2,500)
