Task: Answer the multiple-choice question.
Question: Which compound exhibits a -52.055% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COc1cccc(CNC(=O)C23CN(Cc4ccccc4)CC2C(c2ccc([N+](=O)[O-])cc2)=NO3)c1
b Clc1ccc(-c2nnc(CNC3CC3)o2)cc1
Answer: a. COc1cccc(CNC(=O)C23CN(Cc4ccccc4)CC2C(c2ccc([N+](=O)[O-])cc2)=NO3)c1
