Task: Answer the multiple choice question.
Question: Which compound has a -3.064% 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) CCCCCCn1c(=O)[nH]c2c(c1=O)CCC2
(b) CCOC(=O)C1=C(C)NC2=C(C1c1ccc([N+](=O)[O-])cc1)S(=O)(=O)c1ccccc12
(c) O=c1[nH]c(CSc2nc3ccccc3s2)nc2ccccc12
Answer: a. CCCCCCn1c(=O)[nH]c2c(c1=O)CCC2
