Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(C2C(C#N)=C(N)Oc3cc(O)ccc32)cc1OC?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. 7.155
b. 17.786
c. 2.858
d. 12.639
e. 0.850
Answer: c. 2.858\%.
{#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:
