The correct answer is: B.Primary Succession.

Primary succession occurs in an environment where no previous community existed, such as on bare rock, newly formed land (e.g., after a volcanic eruption), or glacial retreat. It begins from scratch, where there is no soil, and organisms gradually colonize the area. Pioneer species like lichens and mosses are usually the first to arrive, breaking down the rock to form soil, which allows more complex plants and animals to eventually establish themselves.

Here’s why the other terms don’t fit:

A.Climax Community: This refers to the stable, final community that results from the process of succession (whether primary or secondary). It is the endpoint of ecological succession, not the process itself.
