A) lungs
B) eye balls
C) brain
D) uterus
Correct Answer: C
Solution :
Cranium (brain box) is the part of the vertebrate skull that encloses and protects the brain. It is formed by the fusion of several flattened bones which have immovable joints between them. The covering of lungs is known as pleura (pleural membrane). It is a double membrane that lines the thoracic cavity and covers the exterior surface of the lungs. It is a serous membrane forming a closed sac with a small space between the two layers. Eyeball consists of three coats, of which only the outermost is complete. The three layers are tunica fibrosa (outer coat of eyeball), tunica vasculosa (middle coat of eyeball) and tunica nervosa or retina (inner most coat of eyeball). Uterus is organ of female mammals, in which the embryo develops. The innermost layer of uterus is endometrium (mucous membrane) and outermost is myometrium (thick and muscular).
