Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.638\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(-c2noc(CSc3nc(-c4ccccc4)cc(=O)[nH]3)n2)cc1
b: Cc1c(C(=O)N2CCN(c3ccc([N+](=O)[O-])cc3)CC2)sc2ncn(CC(=O)N3CCOCC3)c(=O)c12
c: CC(C)CNC(=O)c1cc(-c2ccc3c(c2)OCO3)on1
Answer: b. Cc1c(C(=O)N2CCN(c3ccc([N+](=O)[O-])cc3)CC2)sc2ncn(CC(=O)N3CCOCC3)c(=O)c12
