Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES O=C1NC(=S)NC(=O)C1=Cc1ccc(Br)s1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] 17.606
[b] 15.035
[c] 5.038
[d] 14.552
Answer: a. 17.606\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
