Problem statement: Answer the multiple choice question.
Question: Which drug has a -3.996% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CCCOc1ccccc1)OCn1nnc2ccccc2c1=O
[b] O=C(COC(=O)c1cnccn1)Nc1ccc(Cl)cc1
Answer: b. O=C(COC(=O)c1cnccn1)Nc1ccc(Cl)cc1
