Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 13.572\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COc1cc(C2C(C(C)=O)=C(O)C(=O)N2Cc2ccccc2)ccc1O
(b) CC1CCN(CCCn2c(=S)[nH]c3c(sc4ccccc43)c2=O)CC1.Cl
Answer: a. COc1cc(C2C(C(C)=O)=C(O)C(=O)N2Cc2ccccc2)ccc1O
