Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES C[N+]1(C)CC2([N+](=O)[O-])CC=C(Oc3ccccc3)C([N+](=O)[O-])(C2)C1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
(a) 13.794
(b) -5.303
(c) -5.132
Answer: a. 13.794%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
