Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.995\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COC(=O)c1sccc1NC(=O)CC1C(=O)NCCN1C(=O)Nc1ccccc1
b: COc1ccccc1C1CC(c2ccco2)=NN1S(C)(=O)=O
c: O=P(c1cccs1)(c1cccs1)c1cccs1
Answer: c. O=P(c1cccs1)(c1cccs1)c1cccs1
{#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#}
O=P(c1cccs1)(c1cccs1)c1cccs1
O=P(c1cccs1)(c1cccs1)c1cccs1
