Hint:-A forest fire also called wildfire is an unplanned and uncontrolled fire in an area of combustible vegetation. It can also be classified more specifically on the basis of the type of vegetation present as a forest fire, brush fire, desert fire, grass fire, peat fire, prairie fire, vegetation, or veld fire.

Complete answer:
The Marchantiophyta is a division of non-vascular land plants also referred to as hepatics or liverworts. They have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. They do not produce seeds (Produce spores for reproduction), flowers, fruit, or wood, and even lack vascular tissue. About 9000 species of liverworts are known across the globe. But most species are leafy with a form very much like a flattened moss rest of the species grow as a flattened leafless called thallus. Leafy species are distinguished from similar mosses based on some features, including their single-celled root-like structures called rhizoids. Leafy liverworts leaves may contain marginal cilia but never have a costa. Other features like the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly differentiated stem and leaves all point to the plant being a liverwort.
Thus, the right option is A.

Note:- While in the case of severely burned forest areas, the residual vegetation will take a lot of time to regenerate themselves while the ferns can easily grow in such burning accidents as fern plants need dry soil and a minimum amount of resources for their growth and development.
