Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CCO[C@H]1OC(C(=O)N2CCN(C)CC2)=C[C@@H](C2CC2)[C@@H]1CCCO?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 6.446
b 15.488
Answer: b. 15.488\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
Constraint: You must return none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{herg_central_at_1uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_1uM#}{herg_central_at_1uM__units}.
CCO[C@H]1OC(C(=O)N2CCN(C)CC2)=C[C@@H](C2CC2)[C@@H]1CCCO
CCO[C@H]1OC(C(=O)N2CCN(C)CC2)=C[C@@H](C2CC2)[C@@H]1CCCO
