Task: Answer the multiple choice question.
Question: Which compound exhibits a -3.624\% 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 other words.
Options:
a: O=C(NCc1ccco1)c1cc(-c2cccc(Cl)c2)on1
b: CCc1ccc(/C=C/C(=O)c2cc(Br)ccc(=O)c2O)cc1
c: CCCCOC(=O)CCCc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
d: Cc1ccc(NS(=O)(=O)c2ccc(NC(=O)CN(c3cc([N+](=O)[O-])ccc3C)S(C)(=O)=O)cc2)c(C)c1
Answer: c. CCCCOC(=O)CCCc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
