Problem statement: 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(C1CC(=O)N(c2ccc(Br)cc2)C1)N1CCCC1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a: 4.460
b: -1.734
Answer: a. 4.460\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
