Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.098\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCOCC(=O)Nc1cc(C(=O)OC)cc(C(=O)OC)c1
(b) O=C(Nc1ccc(S(=O)(=O)Nc2ccccn2)cc1)c1cccc([N+](=O)[O-])c1
Answer: b. O=C(Nc1ccc(S(=O)(=O)Nc2ccccn2)cc1)c1cccc([N+](=O)[O-])c1
