Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.641\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CN(C(=O)c1cc([N+](=O)[O-])ccc1N1CCCC1)C1CCCCC1
b: CN(C)Cc1ccc(CNC(=O)c2ccc(Cl)c(S(=O)(=O)NC3CC3)c2)cc1
c: O=C(c1cc(-c2cccs2)on1)N1CCN(c2ccc(F)cc2)CC1
Answer: a. CN(C(=O)c1cc([N+](=O)[O-])ccc1N1CCCC1)C1CCCCC1
