Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -18.788\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC(C)c1ncc(C(O)c2cccc3ccccc23)n1C
[b] O=C(Nc1ccc([N+](=O)[O-])cc1)/C(=C/c1cccc([N+](=O)[O-])c1)NC(=O)C1CCCCC1
[c] CCOc1ccc(N(C(C)C(=O)NC(C)CC)S(C)(=O)=O)cc1
Answer: b. O=C(Nc1ccc([N+](=O)[O-])cc1)/C(=C/c1cccc([N+](=O)[O-])c1)NC(=O)C1CCCCC1
