Task: Answer the multiple-choice question.
Question: Which drug exhibits a -53.481% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(NCC1CCN(C(=O)c2cccc([N+](=O)[O-])c2)CC1)c1cccc([N+](=O)[O-])c1
(b) CC(=O)c1ccc(S(=O)(=O)NCCC(=O)OCC(=O)NCCc2ccccc2)cc1
Answer: a. O=C(NCC1CCN(C(=O)c2cccc([N+](=O)[O-])c2)CC1)c1cccc([N+](=O)[O-])c1
