Solution

The correct option is B Succession

Plant species, through time undergo non-seasonally and directional cumulative change in a given area.

A disturbance in a given area is the primary reason of a place getting devoid of vegetation, resulting in start of succession. The cause of disturbance might be wind storms, fires, volcanic eruptions, severe flooding, pest infestation, etc. Succession completes when the species don’t change in the given area at that particular time. The community at that time is called as climax community.
