Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CCOC(=O)c1c(-c2cccc([N+](=O)[O-])c2)csc1NC(=O)C1CCCCC1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
a: 22.938
b: 9.922
c: 22.255
d: -4.374
Answer: a. 22.938%.
