The correct answer is:
D

Pioneer Species (I & II): Along with lichens, they are the first organisms to colonise bare rocks. They decompose or weather these rocks, creating a substrate suitable for higher plants.

Soil Protection (III & IV): They grow in dense strands forming a mat or carpet-like structure on the soil. These mats reduce the impact of falling rain and act as soil binders to prevent erosion
