Problem statement: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1OC?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a: 8.993
b: 2.888
c: 10.035
d: 6.863
Answer: b. 2.888\%.
{#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}.
COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1OC
COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1OC
