Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.057\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CCOC(=O)C1=C(O)C(Nc2nccs2)(C(F)(F)F)N=C1C
b) COC(=O)c1c(-c2ccc3ccccc3c2)csc1NC(=O)Cc1ccc(OC)c(OC)c1
Answer: a. CCOC(=O)C1=C(O)C(Nc2nccs2)(C(F)(F)F)N=C1C
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
