The rock formations are the result of the weathering of the big and large rocks by wind and water erosion. The conclusion is that rocks were part of a slow underwater eruption.
<h3>What is the formation of the rocks?</h3>
Rocks can be formed due to volcanic eruptions as when the magma of the volcano rises outwards but, in the underwater surfaces, the magma can't completely rise to the outer surface and faces some pressure.
The oceanic water creates very heavy pressure on the magma of the volcanoes causing them to form some unusual structures that later solidifies into rocks.
Therefore, option A. is part of a slow underwater eruption.
