Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COC(=O)COc1cccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)c1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a: 14.204
b: 23.217
c: 20.172
d: -0.547
Answer: c. 20.172\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
