Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.978\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCCCN(C(=O)c1ccc([N+](=O)[O-])o1)c1c(N)n(CCCC)c(=O)[nH]c1=O
b: Cc1cc(C(=O)N=Nc2c(O)n(C(C)C)c3ccccc23)n[nH]1
c: COc1cccc(C(=O)NNC(=O)c2ccc3ccccc3c2O)c1
Answer: a. CCCCN(C(=O)c1ccc([N+](=O)[O-])o1)c1c(N)n(CCCC)c(=O)[nH]c1=O
