Task: Answer the multiple-choice question.
Question: Which drug has a 13.651\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCOC(=O)NC(=O)/C(C#N)=N\Nc1cccc(OC)c1
(b) CC(C)(C)c1ccc(C(=O)N2CCN(c3ncccn3)CC2)cc1
Answer: a. CCOC(=O)NC(=O)/C(C#N)=N\Nc1cccc(OC)c1
