Task: Answer the multiple choice question.
Question: Which compound exhibits a -3.681\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CSc1ccc(C2Nc3cccc4cccc(c34)N2)cc1
b.) C/C(=N\N1C(=O)c2ccccc2NC1c1ccccc1)c1ccccc1O
c.) CCCCn1c(N)c(N(CC(C)C)C(=O)c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)c(=O)[nH]c1=O
d.) Cc1nn(-c2ccccc2)c(C)c1C(=O)OCc1ccc(C#N)cc1
Answer: c. CCCCn1c(N)c(N(CC(C)C)C(=O)c2ccc(-c3ccc([N+](=O)[O-])cc3)o2)c(=O)[nH]c1=O
