Cell wall is presents in members of fungi and plantae.
Mitochondria are the powerhouse of the cell in all kingdoms except monera.
Pseudopodia are locomotory and feeding structures in sporozoans.
Mushrooms belongs to Basidiomycetes.
Pseudopodia are the finger-like projections and are the locomotory organs of protozoans. For example, Amoeba. Cell wall is present in the members of both kingdom Fungi and Plantae. Fungi have a cell wall made up of chitin and fungal cellulose in some members while plants cell wall is made up of cellulose and hemicellulose. Mitochondria are called the powerhouse of the cell because these are associated with cellular respiration. Mitochondria is present only in eukaryotes and absent in prokaryotes i.e. in members of kingdom Monera. Mushrooms belong to the class Basidiomycetes of kingdom Fungi. For example, Agaricus. So, the correct answer is option A.
