Task: Answer the multiple-choice question.
Query: Which compound exhibits a -2.687\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) Cc1cc2cc(CN(CC3CCCO3)C(=S)NCc3ccco3)c(=O)[nH]c2cc1C
b) COc1cc(C(=O)NCCC(=O)NC2CCCCC2)cc(OC)c1OC
c) O=C1CN(C(=O)c2ccc(Cl)c(S(=O)(=O)N3CCc4ccccc43)c2)c2ccccc2N1
d) COc1cccc(C2/C(=C(/O)c3ccccc3)C(=O)C(=O)N2Cc2ccco2)c1
Answer: c. O=C1CN(C(=O)c2ccc(Cl)c(S(=O)(=O)N3CCc4ccccc43)c2)c2ccccc2N1
