Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.016% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1cccc(NC(=O)C2CCCN(S(=O)(=O)c3ccc(-n4cnnn4)cc3)C2)c1
(b) O=C(Nc1ccccc1)C1CC(O)CN1S(=O)(=O)c1ccc([N+](=O)[O-])cc1
(c) Cn1c(=O)cc(OCC(=O)NCCc2ccc(Cl)cc2)c2ccccc21
Answer: b. O=C(Nc1ccccc1)C1CC(O)CN1S(=O)(=O)c1ccc([N+](=O)[O-])cc1
