Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.823\% 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: CCN1C(=O)CC(N2CCN(c3ccc(Cl)cc3)CC2)C1=O
b: CCC(=O)NC(/C=C/c1ccccc1)c1cc([N+](=O)[O-])c2cccnc2c1O
c: Cn1c(=O)[nH]c2ncn(C)c2c1=O
Answer: a. CCN1C(=O)CC(N2CCN(c3ccc(Cl)cc3)CC2)C1=O
