Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.633% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COc1ccc(S(=O)(=O)N2CCN(C)CC2)cc1Br
b CCCC/C(C)=N\NC(=O)CNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
Answer: a. COc1ccc(S(=O)(=O)N2CCN(C)CC2)cc1Br
