Problem statement: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES Cn1c(=O)c2c(O)c([N+](=O)[O-])c(=O)n(C)c2n(C)c1=O?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: -3.296
b: 11.044
c: 18.055
Answer: c. 18.055%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
