Task: Answer the multiple-choice question.
Query: Which compound has a 7.691% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCCCCn1c(N)c(-c2nc3ccccc3o2)c2c([N+](=O)[O-])nn(CC)c(=O)c21
[b] CCOc1cc(CNCCO)cc(Br)c1OCc1ccccc1.Cl
[c] CC(CN1CCN(C/C=C/c2ccccc2)CC1)c1ccccc1.O=C(O)C(=O)O
Answer: a. CCCCCn1c(N)c(-c2nc3ccccc3o2)c2c([N+](=O)[O-])nn(CC)c(=O)c21
