Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.867\% 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) CC(C)=CC(=O)OCC(=O)NC(=O)NC(C)(C)C
(b) CCCC(C(=O)NC(C)(C)C)N(C(=O)c1snc(C(N)=O)c1N)c1ccc2c(c1)OCCO2
Answer: a. CC(C)=CC(=O)OCC(=O)NC(=O)NC(C)(C)C
{#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}?
