Task: Answer the multiple choice question.
Question: Which compound exhibits a -41.904% 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 additional words.
Options:
(a) COc1ccc(-c2cc(C#N)nc(N3CCNCC3)n2)cc1
(b) O=Cc1[nH]c2ccccc2c1N(C(=O)CCl)c1ccc([N+](=O)[O-])cc1
(c) COc1ccc(/C=C2\CCCC(C(=O)C(F)(F)F)=C2O)cc1
Answer: b. O=Cc1[nH]c2ccccc2c1N(C(=O)CCl)c1ccc([N+](=O)[O-])cc1
