Problem statement: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES CN(C)/C=c1\sc2c(C#N)cc(C(=O)c3ccc(Br)cc3)n2c1=O?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
[a] 3.428
[b] 13.391
[c] 1.514
Answer: a. 3.428\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
