Problem statement: Answer the multiple choice question.
Query: Which compound has a 4.694\% 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, or d without using any other words.
Options:
a: O=C1NC(=O)N(c2ccccc2)C(=O)/C1=C\c1ccccc1[N+](=O)[O-]
b: COc1ccc(S(=O)(=O)N2CCN(c3cccc(C)c3C)CC2)cc1
c: COc1ccc(OC)c(-n2nnnc2SCC(=O)NCc2ccc3c(c2)OCO3)c1
d: C=CCn1c(SCc2nnc(-c3ccccc3)o2)nnc1C(O)c1ccccc1
Answer: b. COc1ccc(S(=O)(=O)N2CCN(c3cccc(C)c3C)CC2)cc1
