Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.603\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)cc1OC
b.) O=C(NCc1ccc2c(c1)OCO2)c1cccs1
Answer: a. COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)cc1OC
{#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#}
COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)cc1OC
