Task: Answer the multiple choice question.
Question: Which drug exhibits a -65.649% 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 additional words.
Options:
a. O=C(CN1CCN(c2ccc([N+](=O)[O-])cc2)CC1)Nc1nccs1
b. O=C(Oc1ccc(N(Cc2cccs2)C2=NS(=O)(=O)c3ccccc32)cc1)c1ccc(Cl)cc1
c. COc1ccc(N2CCN(C(=O)Cc3ccc(Cl)cc3)CC2)cc1
Answer: a. O=C(CN1CCN(c2ccc([N+](=O)[O-])cc2)CC1)Nc1nccs1
