Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 15.609\% 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: CC(=O)N(C(C)=O)c1ncc2c([nH]c3ccccc32)c1C#N
b: O=C(N=Nc1c(O)n(Cc2ccccc2)c2ccccc12)c1ccncc1
Answer: a. CC(=O)N(C(C)=O)c1ncc2c([nH]c3ccccc32)c1C#N
