All living beings grow by the cell division and metabolic processing like respiration, nutrition etc. The living being is made up of cells hence their division happens inside the body and thus the growth happens from inside.

Viruses are obligate parasites. They are acellular and are only made of a genetic material surrounded by a protein capsid. Viruses use the host cellular machinery for survival and replication. They also undergo mutation within the host. They have no energy metabolism nor do they produce waste products. Hence they are considered non-living. Thus the correct answer is option C.

The living organisms are made up of the cells in which the atom forms the basis of all the structures in the cells like the proteins, lipids, fats, nucleic acids, etc. The living organisms are composed of cells, tissues, and ATP as the common source of energy. The non-living things are made up of the atoms which form the material. 

The living organisms are composed of cells which form the tissues. The tissues when damaged are repaired and replaced by the new cells. Irritability is the ability of an organism to respond to the external stimulus. The organism exhibit movement on receiving the stimulus from the internal or the external environment. The most common example of irritability is shown by the Mimosa plant which folds the leaflets on stimulus with touch. 

• Homoeostasis is the process that helps to maintain an equilibrium between the processes or the concentration of the fluid inside and outside the body.
• The process of homeostasis can be achieved by morphological adaptation in the form of gills or through physiological adaptation by a change in temperature or through behavioral adaptation to survive in extreme conditions.
