Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.445\% 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. COCCNC(=O)Cn1nc(Cc2ccncc2)c2ccccc2c1=O
b. CCOC(=O)/C(C#N)=C/c1cn(CCC(=O)O)nc1-c1ccc(Cl)cc1
Answer: b. CCOC(=O)/C(C#N)=C/c1cn(CCC(=O)O)nc1-c1ccc(Cl)cc1
{#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}?

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCOC(=O)/C(C#N)=C/c1cn(CCC(=O)O)nc1-c1ccc(Cl)cc1
CCOC(=O)/C(C#N)=C/c1cn(CCC(=O)O)nc1-c1ccc(Cl)cc1
