Problem statement: Answer the multiple choice question.
Query: Which compound has a -16.775% 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] O=C(N/C(=C/c1ccccc1F)C(=O)N1CCCCC1)c1ccccc1
[b] CCCn1c(=O)[nH]c(=O)c2c1nc(-c1cc([N+](=O)[O-])ccc1Cl)n2CCOC
[c] CCCn1c(SCC(=O)Nc2cc(Cl)ccc2Cl)n[nH]c1=O
Answer: b. CCCn1c(=O)[nH]c(=O)c2c1nc(-c1cc([N+](=O)[O-])ccc1Cl)n2CCOC
