Task: Answer the multiple-choice question.
Query: Which drug exhibits a -13.892\% 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 other words.
Options:
[a] Cc1ccc(N=Cc2c(O)n(-c3cc(Cl)ccc3N3CCOCC3)c(=O)c3ccccc23)cc1C
[b] Cn1cc(S(=O)(=O)Nc2cccc3ccccc23)c(=O)n(C)c1=O
[c] C=C(C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@H](C(N)=O)N(C(=O)c2ccccc2)C3)c1
Answer: b. Cn1cc(S(=O)(=O)Nc2cccc3ccccc23)c(=O)n(C)c1=O
