Task: Answer the multiple-choice question.
Question: Which drug exhibits a -37.548% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=c1c2ccc([N+](=O)[O-])cc2ncn1CCOc1ccc(Cl)cc1
(b) CC(=O)Nc1ccc(S(=O)(=O)NC2CC(=O)N(c3cccc(F)c3)C2)cc1
(c) Cc1ccc(S(=O)(=O)Nc2nc3ccccc3s2)cc1[N+](=O)[O-]
Answer: a. O=c1c2ccc([N+](=O)[O-])cc2ncn1CCOc1ccc(Cl)cc1
