Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -3.429% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOC(=O)C1=C(c2ccccc2)OC(N)=C(C#N)C1C(C)C
(b) CCOc1c(C#N)c(C#N)c2nc(C)cc(C)n12
Answer: a. CCOC(=O)C1=C(c2ccccc2)OC(N)=C(C#N)C1C(C)C
