Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.226\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. COc1cccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cc(C)on2)c1
b. c1cc2c3c(cccc3c1)NC1(CCCCCC1)N2
Answer: a. COc1cccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cc(C)on2)c1
{#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#}
COc1cccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cc(C)on2)c1
COc1cccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2cc(C)on2)c1
