Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.669\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCc1ccc(C2CC(c3ccccc3Cl)Nc3nc(N)nn32)cc1
[b] CC(=O)C1=C(C)NC(SCc2cccc3ccccc23)=C(C#N)C1c1ccco1
Answer: b. CC(=O)C1=C(C)NC(SCc2cccc3ccccc23)=C(C#N)C1c1ccco1
{#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#}
CC(=O)C1=C(C)NC(SCc2cccc3ccccc23)=C(C#N)C1c1ccco1
CC(=O)C1=C(C)NC(SCc2cccc3ccccc23)=C(C#N)C1c1ccco1
