Best answer
The correct option is (c) Lichens

For explanation: The first biotic community to invade a bare land or area is known as the pioneer community. In a xerarch succession, lichens in the temperate region act as pioneering species. Some examples of lichens are Rinodina, Lecanora, Parmelia, etc.
