The borders (coastlines) of the continents underwent a number of changes
since the split. Often, chunks of land were washed away with water,
slowly or in bigger portions. The coast was generally "smoothed" by the
ocean currents too, and in some places more land was added with the
material that the ocean currents brought.
Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.
Relative dating best helps determine fossil age. It's where layers of sedimentary rock and fossils pile up on top of each other; the oldest fossils being in the bottom layer and the youngest in the top.
Based on the cladogram, the organisms that are most related are A and C since they had the most recent divergence.
<h3>What is a cladogram?</h3>
A cladogram is a diagram which is tree-like showing similarities and differences among organisms as a result of evolutionary changes that occur in the organisms.
In a cladogram, the most similar organisms have the most recent branching along the cladogram.
Based on the description of the cladogram, the most recent branching occurred between A and C.
Therefore, based on the cladogram, the organisms that are most related are A and C.

The answer is, acquired traits are passed down from parent to offspring.
