Task: Answer the multiple choice question.
Question: Which compound exhibits a -4.578\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCn1cnc2c1c(=O)n(CC(=O)Nc1cc(C)on1)c(=O)n2Cc1ccccc1
b: O=C1C(Cl)=C(Nc2cccc(O)c2)C(=O)N1Cc1ccccc1
Answer: b. O=C1C(Cl)=C(Nc2cccc(O)c2)C(=O)N1Cc1ccccc1
