Problem statement: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES O=C(Nc1ccc(C(F)(F)F)cc1Cl)c1ccc(Cn2cc(Br)cn2)o1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a. 1.859
b. 4.814
c. 4.921
Answer: a. 1.859\%.
{#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(Nc1ccc(C(F)(F)F)cc1Cl)c1ccc(Cn2cc(Br)cn2)o1
O=C(Nc1ccc(C(F)(F)F)cc1Cl)c1ccc(Cn2cc(Br)cn2)o1
