Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.632\% 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(O)c1ccc(NC(=O)c2cccc(C(=O)Nc3ccc(C(=O)O)cc3)c2)cc1
b: CCOc1cc(/C=C2/SC(=S)NC2=O)ccc1OC(=O)c1ccco1
c: Cn1c(O)c(N=NC(=O)c2cccc(S(=O)(=O)N3CCCCC3)c2)c2ccccc21
d: CCCCC(=O)Nc1c(C)cc(C)cc1Cl
e: O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Br)cc1
Answer: e. O=C(C/C=N\OCc1ccc([N+](=O)[O-])cc1)Nc1ccc(Br)cc1
