Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.259\% 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)n1c(-c2ccccc2)c(-c2ccccc2)n(C)c1=O
[b] Cc1ccc(-c2csc(NC(=O)C3=NN(c4ccccc4)C(=O)CC3)n2)cc1
Answer: a. CC(=O)n1c(-c2ccccc2)c(-c2ccccc2)n(C)c1=O
