Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.002\% 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. COc1ccc(C2NC3=C(CCCC3)C(C#N)(C#N)C2(C#N)C#N)cc1
b. CC(=O)c1ccc(S(=O)(=O)N2CCN(CC#N)CC2)cc1
Answer: a. COc1ccc(C2NC3=C(CCCC3)C(C#N)(C#N)C2(C#N)C#N)cc1
