Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES CN(C)c1ncnc2c1NC1=C(S2)C(=NCCCC(=O)O)CC(C)(C)C1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] -39.078
[b] 0.211
Answer: b. 0.211\%.
{#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:
