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 compound with the SMILES O=C(c1cc(N2CCOCC2)c(F)cc1[N+](=O)[O-])N1CCOCC1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] -1.883
[b] 12.567
[c] 9.971
[d] -8.636
Answer: b. 12.567\%.
{#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=C(c1cc(N2CCOCC2)c(F)cc1[N+](=O)[O-])N1CCOCC1
O=C(c1cc(N2CCOCC2)c(F)cc1[N+](=O)[O-])N1CCOCC1
