Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.459\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] N#C/C(=C\c1cccs1)C(=O)NCc1ccccc1
[b] O=[N+]([O-])c1ccc(N2CCN(CC3CCCCC3)CC2)cc1
[c] CN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)CN1C(=O)NC2(CCCC2)C1=O
[d] O=C(NC(=S)Nc1ccc(S(=O)(=O)Nc2nccs2)cc1)c1cccc(F)c1
[e] CCc1nnc(NC(=O)CCC2CCCCC2)s1
Answer: a. N#C/C(=C\c1cccs1)C(=O)NCc1ccccc1
