Solution

The answer is option (c).

Deficiency disease is a disease which arises due to the lack of nutrients in our diet over a long period of time, e.g. scurvy, rickets, beriberi, anaemia and goitre.

To prevent these diseases, it is essential to have a balanced diet. It is a diet, which contains adequate amounts of all the nutrients as well as sufficient quantity of water and roughage.
