Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 13.309\% human ether-à-go-go related gene (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] CCCCCC(=O)NNC(=S)NC(C)=O
[b] CCCCN1C(=O)NC(c2cccc([N+](=O)[O-])c2)C(C(=O)OCC)=C1C
Answer: a. CCCCCC(=O)NNC(=S)NC(C)=O
