Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(CC2(C)OC(c3ccc([N+](=O)[O-])cc3)=NN2C(C)=O)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: 18.183
b: 10.498
c: -6.661
Answer: c. -6.661\%.
{#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}.
COc1ccc(CC2(C)OC(c3ccc([N+](=O)[O-])cc3)=NN2C(C)=O)cc1
COc1ccc(CC2(C)OC(c3ccc([N+](=O)[O-])cc3)=NN2C(C)=O)cc1
