The statement that best describes how the constraints of Project Apollo were prioritized is:
Time and safety were prioritized over cost, so solutions to problems often cost more than planned.
During Project Apollo, achieving the goal of landing humans on the Moon by a specific deadline was a critical driver. Safety was also of paramount importance, especially given the risks involved in human spaceflight. As a result, when challenges arose, the program often opted for solutions that ensured safety and adhered to the timeline, even if those solutions resulted in increased costs.
