Task: Answer the multiple choice question.
Query: Which compound has a -2.696\% 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 other words.
Options:
[a] CN1C(=O)Cc2cc(S(=O)(=O)NCCc3ccc(Cl)cc3)ccc21
[b] O=C(CCNC(=O)c1ccc([N+](=O)[O-])cc1)Nc1ccc(F)cc1
[c] O=C(NCc1ccc(Cl)c(Cl)c1)c1cccnc1
[d] O=[N+]([O-])c1ccc2c(OCc3nnc(-c4ccccc4Br)o3)ncnc2c1
Answer: a. CN1C(=O)Cc2cc(S(=O)(=O)NCCc3ccc(Cl)cc3)ccc21
