Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.851\% human ether-à-go-go related gene (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: COC(=O)CSc1nnc(-c2ccoc2C)n1-c1ccc(C)cc1
b: O=C(NC(=S)Nc1ccc(NC(=O)c2cccs2)cc1)c1ccc([N+](=O)[O-])cc1
c: Cc1ccc(N2C(=O)C3C4C=CC(C4)C3C2=O)cc1C
Answer: b. O=C(NC(=S)Nc1ccc(NC(=O)c2cccs2)cc1)c1ccc([N+](=O)[O-])cc1
