Answer 2

Answer:

A = Heart

B = RED

C = Blood is a liquid, which has cells of various kinds suspended in it.The fluid part of the blood is called plasma.

One type of cells are the red blood cells (RBC) which contain a red pigment called haemoglobin. Haemoglobin binds with oxygen and transports it to all the parts of the body and ultimately to all the cells. It will be difficult to provide oxygen efficiently to all the cells of the body without haemoglobin. The presence of haemoglobin makes blood appear red

D = platelets.
