Macrophages are . cells that induce the lysis of virus-infected body cells large, phagocytic cells that can leave the circulation and enter the tissues of the body the best defense against parasites short-lived cells that self-destruct soon after engulfing foreign invaders antigen-presenting cells that originate from neutrophils

Phagocytic cells that can leave the circulation and enter the tissues of the body.

Explanation:

A macrophage is a type of phagocytic cell that has been differentiated from monocytes that is involved in the detection, phagocytosis, and destruction of harmful ogansms and pathogens. They originate from monocytes which was produced in the blood and then migrate to exist within specific organs/ tissues in the body. They kill their prey by engulfing them and kiling them using acid and they also present antigenic fragments to the T lymphocytes.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
