Problem statement: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES O=c1[nH]c(=S)[nH]c(O)c1N=Nc1cc2c(cc1[N+](=O)[O-])OCO2?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
(a) 7.817
(b) 8.951
(c) -2.333
(d) 16.943
Answer: a. 7.817\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
