Detailed explanation-1: -Phagocytosis is also called cell eating. It refers to intake of solid food particles by an animal cell. It is not shown by cells which are surrounded by a cell wall like a plant cell or a prokaryotic cell. Phagocytosis is a type of endocytosis.

Detailed explanation-2: -Phagocytosis is a cellular process for ingesting and eliminating particles larger than 0.5 m in diameter, including microorganisms, foreign substances, and apoptotic cells. Phagocytosis is found in many types of cells and it is, in consequence an essential process for tissue homeostasis.

Detailed explanation-3: -Larger particles such as microbes, bacteria and cellular debris are internalised in a process called phagocytosis, which you can consider as “cell eating”. While pinocytosis, is performed by almost all cellular types, phagocytosis is pretty much limited to immune cells, like macrophages.

Detailed explanation-4: -In phagocytosis, or “cell eating, ” the cell engulfs debris, bacteria, or other sizable objects. Phagocytosis occurs in specialized cells called phagocytes, which include macrophages, neutrophils, and other white blood cells. Hence, A is the correct option.
