Task: Answer the multiple-choice question.
Query: Which drug exhibits a -8.888\% 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 other words.
Options:
a) CN(CC(=O)NCC(c1ccccc1)N1CCCC1)S(=O)(=O)c1ccc(Cl)cc1
b) COc1cc([N+](=O)[O-])ccc1NC(=O)N1CCCCCC1
c) O=c1cc(N2CCCCC2)c(-c2ccccc2)nn1Cc1ccc(Cl)cc1Cl
Answer: a. CN(CC(=O)NCC(c1ccccc1)N1CCCC1)S(=O)(=O)c1ccc(Cl)cc1
