B. It has been my experience.

The edges of the continents are in a constant state of change caused by the ocean currents. Those currents can bring material with them, making the line more "smooth" and adding land to it, forming the so -called barrier beaches, or the sea can cause the land to fall into the water.
this change of edges over time and tectonic movement mean that the shape of the continents changes all the time: so the continents changed since the time of the split.
Answer:

Explanation:
'strict' and 'harsh' are out because business letters are not meant to insult or criticise, but rather to be courteous (polite). 'fancy' is out because business letters do not use unnecessarily flowery language.

i hope this helps! :D
