Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES COc1ccccc1C1C(C(C)=O)=C(C)N=c2s/c(=C\c3cc(OC)c(OC)c(OC)c3)c(=O)n21?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] 2.958
[b] 4.407
[c] 13.906
[d] 23.473
Answer: a. 2.958%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_10uM__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.
