Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES O=C(NCc1ccccc1)c1cc[n+](CC(=O)c2cccs2)cc1.[Br-]?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a: 16.828
b: -1.157
Answer: b. -1.157\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
