At what time of the day – in the morning, at noon, or in the evening – is the size of a cloud’s shadow on the Earth’s surface closest to the size of the cloud itself?

At noon, because light falls from above, that is, perpendicular to the surface, and the size of the projection is equal to the size of the object. In general, the sun is directly above the surface and therefore the shadows and sizes of the cloud are the same. But in the morning, when the sun is still rising, all the shadows are stretched out. The same is in the evening.
