Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -66.045% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CN1CCCN(c2ccc([N+](=O)[O-])cc2)CC1
(b) O=C(Cc1cc(=O)[nH][nH]1)N/N=C/c1c(Cl)cccc1Cl
(c) COc1ccccc1CCN1CCCC(CN(C)C(=O)CCC(=O)N(C)C)C1
Answer: a. CN1CCCN(c2ccc([N+](=O)[O-])cc2)CC1
