Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.359\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1ccc(S(=O)(=O)Nc2cccc(/C=C/C(=O)O)c2)cc1
[b] Cn1c(N)c(C(C[N+](=O)[O-])c2ccccc2Cl)c(=O)n(C)c1=O
[c] Cc1cc(C)nc(NC(N)=NCCc2c[nH]c3ccccc23)n1
Answer: b. Cn1c(N)c(C(C[N+](=O)[O-])c2ccccc2Cl)c(=O)n(C)c1=O
