Task: Answer the multiple-choice question.
Question: Which drug has a 2.491\% 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 additional words.
Options:
a: N#CC(C#N)=Cc1ccc(OCC(=O)N2CCOCC2)cc1
b: CC(=O)NC(CC(=O)OCC(=O)c1c(N)n(CC(C)C)c(=O)n(C)c1=O)c1ccccc1
Answer: a. N#CC(C#N)=Cc1ccc(OCC(=O)N2CCOCC2)cc1
