The most credible answer may be all five.
Early crews may prioritize self-pollinating crops, human tools and controlled airflow. Robotic systems may reduce repetitive work. Carefully contained biological pollinators become relevant only when crop diversity, habitat scale and ecological ambition justify their additional complexity.
The map is intentionally a comparison framework, not a prediction. Its purpose is to help researchers, students and science-fiction worldbuilders ask what each method requires, what can fail and where redundancy matters.
