Task: Answer the multiple choice question.
Question: Which compound exhibits a -12.940\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])N1CCC(Cc2ccccc2)CC1
b CCN(Cc1ccccc1)S(=O)(=O)c1c[nH]c(C(=O)OC)c1
c NC(=O)c1ccc(NS(=O)(=O)c2ccccc2F)cc1
Answer: a. O=C(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])N1CCC(Cc2ccccc2)CC1
