Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.361\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) COc1cccc(/C=N/NC(=O)c2ccoc2C)c1O
b) CCOC(=O)/C(C#N)=N/Nc1ccccc1C(=O)O
Answer: b. CCOC(=O)/C(C#N)=N/Nc1ccccc1C(=O)O
