Answer:
The correct answer will be option-B
Step-by-step explanation:
Forest moss species mostly belong to the plant group called Bryophytes which represent a group of plants with no vascular system and no flowers. Bryophytes represent the primitive group in the history of the evolution of the plants.
The long green trees belong to higher groups of plant kingdom called gymnosperms and angiosperms which is advanced due to the presence of the vascular tissues.
Since the trees posses vascular tissues which help them absorb and conduct water and minerals from the soil which is absent in the mosses therefore, Option-B is the correct answer.
