Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.331\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) C=C1C(=O)C=C[C@]2(C)C[C@@H]3OC(=O)[C@](C)(O)[C@H]3C[C@@H]12
(b) O=C(O)c1cc(/C=C/c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)nc2ccccc12
(c) COc1ccc(-c2nc(CS(=O)CC(=O)NCc3ccccn3)c(C)o2)cc1
Answer: b. O=C(O)c1cc(/C=C/c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)nc2ccccc12
