Task: Answer the multiple choice question.
Query: Which compound has a 0.271\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(NC1CCCCC1)N(Cc1ccc(F)cc1)Cc1nc2ccccc2c(=O)[nH]1
b: COc1ccc(OCC(=O)NCCc2ccc(S(N)(=O)=O)cc2)cc1
c: CC[N+]1(CC(O)COC2CC(C)CC(C)(C)C2)CCOCC1.[I-]
d: C=Cn1cc[n+](CC(=O)c2ccc(OC)c(OC)c2)c1.[Br-]
e: Cc1cc(C)cc(NC(=O)CSc2ccc(-c3ccccn3)nn2)c1
Answer: b. COc1ccc(OCC(=O)NCCc2ccc(S(N)(=O)=O)cc2)cc1
