Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.588\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC(=O)C1=C(C)N2CCN=C2S1
[b] Cc1ccc(C(=O)O)cc1N1C(=O)c2cccc3cc(Br)cc(c23)C1=O
Answer: a. CC(=O)C1=C(C)N2CCN=C2S1
