Solution

The correct option is B Phagocytosis
Phagocytosis is the process of intake of solid particles such as food, foreign particles, pathogens, etc., across the cell membrane by forming detachable vesicles. Phagocytosis is also called as cell eating. It is frequently used by free protozoans such as amoeba for engulfing food particles and by specialized mammalian cells called as phagocytes for removing damaged cells, fibres, bacteria and dust particles.
Pinocytosis is a process of intake of droplets of extracellular fluid along with sub-microscopic particles across the cell membrane.
Exocytosis is a process of expulsion of materials from the cell.
So, the correct answer is option B.
