Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.490\% 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) O=C(Nc1ccc2c(c1)OCCO2)c1ccco1
b) CCc1ccc(C2NC(=S)NC3=C2C(=O)CC(C)(C)C3)cc1
c) Cc1ccc(NC(=O)CN(C)CC(=O)Nc2ccc(N3CCOCC3)cc2)c([N+](=O)[O-])c1
Answer: b. CCc1ccc(C2NC(=S)NC3=C2C(=O)CC(C)(C)C3)cc1
