A Correct answer
Explanation

Macrophages are cells produced by the differentiation of monocytes in tissues. Amoeboid movement is a crawling type of movement in which the cell forms temporary cytoplasmic projections called pseudopodia (false feet) towards the front of the cell. Leukocytes like phagocytes or macrophages of the lymph show amoeboid movements to engulf antigen or microbes and to immigrate in the circulatory fluid.
