Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.295\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
b. O=C(CCN1CCC(c2ccc(Cl)s2)=N1)c1ccc(Cl)s1
Answer: a. CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
{#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#}
CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
