Task: Answer the multiple-choice question.
Query: Which compound exhibits a -4.559\% 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 additional words.
Options:
[a] O=C(CN1C(=O)COc2ccccc21)NCCCN1CCN(Cc2ccccc2)CC1
[b] CN(C)c1nc2n(c(=O)n1)C(C#N)CS2
[c] O=C(Nc1nc2ccc(Cl)cc2s1)c1ccco1
[d] COc1ccc(N=C2SC(C(=O)O)CC(=O)N2Cc2ccc(OC)c(OC)c2)cc1
[e] COC(=O)c1ccc(CO/N=C/c2cccc([N+](=O)[O-])c2)cc1
Answer: c. O=C(Nc1nc2ccc(Cl)cc2s1)c1ccco1
