Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.492\% 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: CCN(CC)S(=O)(=O)c1ccc(N2CCOCC2)c(NC(=O)C2CC2)c1
b: CCCCC(=O)Nc1cc([N+](=O)[O-])ccc1Cl
c: O=C(COc1ccc([N+](=O)[O-])cc1Cl)NCC1CCCO1
Answer: b. CCCCC(=O)Nc1cc([N+](=O)[O-])ccc1Cl
