Task: Answer the multiple choice question.
Question: Which drug has a 16.142% 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.) CCOC(=O)C(=O)/C(C#N)=C/Nc1ccc(Cl)cc1
b.) Clc1ccc(OCC#CCN2CCCCCC2)cc1.O=C(O)C(=O)O
Answer: a. CCOC(=O)C(=O)/C(C#N)=C/Nc1ccc(Cl)cc1
