Task: Answer the multiple-choice question.
Question: Which drug has a 15.938% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1ccc([N+](=O)[O-])cc1NC(=O)c1ccc(Br)s1
b COC(=O)c1c(NC(=O)c2ccccc2)sc(C(N)=O)c1C
c CCN(CC)CCN1C(=O)C2C(C(=O)Nc3cccc(C)c3)C3C=CC2(O3)C1C(=O)NC1CCCC(C)C1C
Answer: b. COC(=O)c1c(NC(=O)c2ccccc2)sc(C(N)=O)c1C
