Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.192\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(Nc1nc(-c2ccccc2)cs1)Nc1ccc(F)cc1F
b: Nc1nc(Nc2cccc(F)c2)nc(NCc2ccco2)c1[N+](=O)[O-]
Answer: a. O=C(Nc1nc(-c2ccccc2)cs1)Nc1ccc(F)cc1F
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
