Task: Answer the multiple choice question.
Question: Which compound has a 13.437\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1cccc(C2NC(=O)NC(C)=C2C(=O)OCC2CCCCC2)c1
b COc1ccccc1N1CCN(C(=O)c2cc(=O)c3cc(C)ccc3o2)CC1
Answer: a. COc1cccc(C2NC(=O)NC(C)=C2C(=O)OCC2CCCCC2)c1
