Final answer:
When selecting a photo based on the action of jumping on it, the question refers to the function of the objects shown in the photos. The correct answer is D. Function, and this process exemplifies how objects are categorized by their purpose.
Step-by-step explanation:
If shown an array of photos and asked, "Give me the one that you jump on," we are discussing the function of objects depicted in the photos. The correct answer to this question is D. Function. A trampoline would be an example of an object you jump on, and its function is what defines it in this context rather than its class or a specific feature. This demonstrates how objects can be categorized based on their use or purpose.
