Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.676\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=C(O)c1ccc2c(c1)N(Cc1ccccc1)C(=O)c1ccccc1S2=O
b.) O=C(COC(=O)/C=C/c1ccccc1Cl)NC1CCCC1
Answer: a. O=C(O)c1ccc2c(c1)N(Cc1ccccc1)C(=O)c1ccccc1S2=O
{#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}?
