Task: Answer the multiple choice question.
Question: Which drug has a 7.751\% human ether-à-go-go related gene (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: CC1=C(C#N)C(=O)NC(C)(C)C1
b: OC1OC[C@@H](O)[C@H](O)[C@H]1O
Answer: a. CC1=C(C#N)C(=O)NC(C)(C)C1
{#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}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CC1=C(C#N)C(=O)NC(C)(C)C1
