Hint: The change of the fluid to solid inside the cells that’s capable of changing into different forms with the help of cytoplasm. Plasma gel is the more solid or gel like state and plasma sol is only the fluid state present in the cytoplasm. And Sol gel theory that is responsible for amoeba movement with the help of interchange of plasma sol to plasma gel.

Complete answer:
The most common mode of locomotion in the eukaryotic cells is known as amoeboid movement and a type of crawling like movement with the help of cytoplasm after the formation of pseudopodia. When pseudopodia is in front to pull the cell forward, that time movement occurs in the cytoplasm slides, and attached with the action potential during the linked to change in the movement, though the exact mechanism is still unknown.
Therefore slime models, amoeba, amoeba Proteus and leukocytes are the example of organisms that exhibit this type of locomotion. Particularly adept at the amoeboid movement thus leading to their high rate of metastasis in the cancers arising from the connective tissues of the cells that occurred in the process of locomotion.

Therefore the correct option is (A).

Note: The amoeboid process explained by Gold acre and Lorsch. Cell has no feet for the movement with the help of cytoplasmic fluid amoeboid movement occurring inside the cell that is also known as pseudopodia (artificial feet of the cell). That has two important functions in food capture and locomotion provided to the cell.
