Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -4.063\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(COc1ccccc1N1C(=O)c2ccccc2C1=O)c1ccc(Cl)cc1
b NC(=O)CC1NC(=O)c2cc([N+](=O)[O-])cc(I)c2OCCC(C(N)=O)NC(=O)[C@@H]2CCCN2C1=O
Answer: a. O=C(COc1ccccc1N1C(=O)c2ccccc2C1=O)c1ccc(Cl)cc1
