Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.340\% 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: COc1cc([N+](=O)[O-])ccc1-c1ccc(/C=N/NC(N)=O)o1
b: Clc1ccc(-c2n[nH]c3c2CCC3)cc1Cl
Answer: a. COc1cc([N+](=O)[O-])ccc1-c1ccc(/C=N/NC(N)=O)o1
