Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.791\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C1CC(=O)N(Cc2cccs2)C(=O)N1
(b) O=C(c1cccc(Oc2c(Cl)cccc2[N+](=O)[O-])c1)N1CCOCC1
(c) CCOc1cccc(CNn2cnnc2)c1OCc1ccccc1
Answer: b. O=C(c1cccc(Oc2c(Cl)cccc2[N+](=O)[O-])c1)N1CCOCC1
