Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.961% 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: COc1ccc(C(=O)N2CCCC2=O)cc1
b: Cc1ccc(C(c2c(C)nn(-c3ccccc3)c2N)c2c(C)nn(-c3ccccc3)c2N)cc1
Answer: a. COc1ccc(C(=O)N2CCCC2=O)cc1
