Task: Answer the multiple-choice question.
Query: Which drug exhibits a -8.627\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(NC(=O)CN(C)C(C)C(=O)N2CCCCC2)cc1
b: O=C(C1CC(=O)N(c2ccccc2)C1)N1CCN(c2ccc(F)cc2)CC1
Answer: b. O=C(C1CC(=O)N(c2ccccc2)C1)N1CCN(c2ccc(F)cc2)CC1
