Help!

Is anyone able to help me answer this question for my online lab? I’m a bit confused by it. I’m assuming it’s asking which phase of mitosis were the onion root tip cells? But I’m not sure. All the information I’m given is these photos. The first two are x100 and all it says is the black dots indicate a different nucleus and then the 3rd photo is blown up to x1000 and then there’s 2 other photos blown up to x1000 but are essentially the same exact thing.

The original question: In which stage were most of the onion root tip cells? How would you explain this finding?|
