Task: Answer the multiple choice question.
Query: Which compound has a -0.642\% 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, c, d, or e without using any other words.
Options:
(a) O=C(COc1ccc(S(=O)(=O)NC2CCCC2)cc1)N1CCCCC1
(b) CC(C)(C)n1nnnc1C(c1cccs1)N1CCN(Cc2ccccc2)CC1.Cl
(c) COc1cccc(NC(=O)CCNS(=O)(=O)c2ccc3c(c2)oc(=O)n3C)c1
(d) CC(=O)Nc1ccc(S(=O)(=O)NC2CC3CCC2C3)cc1
(e) CC(C)N1CCN(Cc2ccccc2-c2ccco2)CC1CCO
Answer: b. CC(C)(C)n1nnnc1C(c1cccs1)N1CCN(Cc2ccccc2)CC1.Cl
