Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.176\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3ccsc3)C2C1
b. CC(=O)Nc1ccc(S(=O)(=O)NC(CC(=O)NCCc2ccccc2)C(C)C)cc1
Answer: a. CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3ccsc3)C2C1
{#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#}
CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3ccsc3)C2C1
CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3ccsc3)C2C1
