Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.239\% 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) Nc1ccc(NC(=O)c2ccccc2)c2c1C(=O)c1ccccc1C2=O
b) CCOc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC
Answer: a. Nc1ccc(NC(=O)c2ccccc2)c2c1C(=O)c1ccccc1C2=O
