Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES Cc1c(CBr)[n+](=O)c2c(n1[O-])C(Br)CCC2Br?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] 10.048
[b] 17.593
[c] 9.857
[d] 1.365
Answer: b. 17.593\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
