Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.531% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(Cn1c(=O)c2ccccc2n(CC(=O)N2CCCCC2)c1=O)N1CCCCC1
(b) Oc1ccccc1N=N/C(=N/Nc1ccccc1O)c1ccccc1
(c) CCOC(=O)CC1=C(C(=O)OCC)C(c2cccnc2)C(C#N)=C(N)O1
Answer: c. CCOC(=O)CC1=C(C(=O)OCC)C(c2cccnc2)C(C#N)=C(N)O1

{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_10uM#}{herg_central_at_10uM__units} {herg_central_at_10uM__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_10uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCOC(=O)CC1=C(C(=O)OCC)C(c2cccnc2)C(C#N)=C(N)O1
CCOC(=O)CC1=C(C(=O)OCC)C(c2cccnc2)C(C#N)=C(N)O1
