Task: Answer the multiple-choice question.
Query: Which drug has a -20.882% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(CCCc1nc2ccccc2s1)N1CCN(c2ccccc2)CC1
b COC(=O)C1=C(C)N(CCc2ccc(OC)cc2)C(=O)C1
Answer: b. COC(=O)C1=C(C)N(CCc2ccc(OC)cc2)C(=O)C1
