Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.082\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. NS(=O)(=O)c1ccc(NC(=S)NC2CCCCCC2)cc1
b. O=C(Oc1nsnc1N1CCOCC1)N1CCOCC1
Answer: b. O=C(Oc1nsnc1N1CCOCC1)N1CCOCC1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
