Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.396\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1cccc(N2C(=O)C(Cc3ccccc3)NC2=S)c1
b: CCCCCc1ccc(-c2cn(CCCOCc3ccccc3)nn2)cc1
Answer: a. Cc1cccc(N2C(=O)C(Cc3ccccc3)NC2=S)c1
