Task: Answer the multiple-choice question.
Question: Which compound exhibits a -1.696\% 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 NNC(=O)C1=NOC(CNc2ncc(C(F)(F)F)cc2Cl)C1
b Cc1ccc(OCc2nnc(SCC(=O)c3ccccc3)n2Cc2ccco2)cc1
c CN1CCC(=NNc2ncnc3sc4c(c23)CCCC4)CC1
d COc1ccc(S(=O)(=O)N2CCN(CC(=O)Nc3cc(Cl)ccc3Cl)CC2)cc1
e CC(=O)Nc1ccc(NC(=O)C(C)Sc2n[nH]c(-c3cccs3)n2)cc1
Answer: a. NNC(=O)C1=NOC(CNc2ncc(C(F)(F)F)cc2Cl)C1
