Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.823\% 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 other words.
Options:
a: CCOc1ccc(OCC(=O)OCC(=O)NNC(=O)c2ccc([N+](=O)[O-])cc2)cc1
b: O=C(COC(=O)Cn1cnc2ccccc2c1=O)Nc1ccccc1Sc1ccc(Cl)cc1
Answer: a. CCOc1ccc(OCC(=O)OCC(=O)NNC(=O)c2ccc([N+](=O)[O-])cc2)cc1
