Task: 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 O=c1[nH]c(Cc2ccc(F)cc2)nc2scc(-c3ccc(F)cc3)c12?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] 15.435
[b] 7.293
Answer: a. 15.435\%.
{#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}.
O=c1[nH]c(Cc2ccc(F)cc2)nc2scc(-c3ccc(F)cc3)c12
O=c1[nH]c(Cc2ccc(F)cc2)nc2scc(-c3ccc(F)cc3)c12
