Solution
The correct option is B bryophytes
Lichens invade the rocks and break rocks to form soil. Mosses, which are bryophytes, grow to trap moisture. They form dense mats on the soil and reduce the impact of falling rain. They also prevent soil erosion. Both mosses and lichens decompose the rocks and make the substrate suitable for the growth of higher plants. This process is known as ecological succession.
