Task: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES O=C(Nc1ccc(NC(=O)N2CCN(c3ccccc3O)CC2)cc1)N1CCN(c2ccccc2O)CC1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 21.685
b 0.695
Answer: a. 21.685%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
