a. rate of expansion.

Explanation:

The various theories of the final destination of the universe depend on the current current of the universe, known as the rate of expansion.

We then use the term expansion rate which is related to the measure of how much the total space of the universe has increased over time. It is also necessary to clarify that relativity only restricts the speed at which bodies move through space, but it does not in any way restrict the rate at which space changes in size. One of the effects of the expansion of the Universe is to make us see the galaxies around us moving away from us. In addition, this distance speed is proportional to the distance between us and the observed astronomical object. This means that an object that is more distant moves away from us faster than another that is closer

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
