Task: Answer the multiple choice question.
Query: Which compound has a -0.192\% 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) CCCCNC(=O)C(Sc1ccccc1)c1ccccc1
(b) CNC(=O)CSc1nc2c([nH]c3ccccc32)c(=O)n1CCOC
(c) CN1CCN(S(=O)(=O)c2ccc([N+](=O)[O-])cc2)CC1
(d) CCN(CC1CCCO1)C(=O)CCc1nnc(CCc2ccccc2OC)o1
(e) CCOc1ccc(CCNC(=O)COC(=O)/C=C/c2ccc(OC(F)F)c(OC)c2)cc1OCC
Answer: b. CNC(=O)CSc1nc2c([nH]c3ccccc32)c(=O)n1CCOC
