Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 15.384\% 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 other words.
Options:
a.) O=Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ncccn12
b.) COC(=O)CC1=C(C(=O)OC)C2(C(=O)Nc3c(C)cccc32)C(C#N)=C(N)O1
Answer: b. COC(=O)CC1=C(C(=O)OC)C2(C(=O)Nc3c(C)cccc32)C(C#N)=C(N)O1
