Understanding Deficiency Diseases
Deficiency diseases occur when the body lacks essential nutrients necessary for maintaining health. Let's break down the statements to understand why option 'C' (ii and iv) is the correct answer.
Statement Analysis
- (i) They are caused by germs.
This statement refers to infectious diseases, not deficiency diseases. Infectious diseases are caused by pathogens like bacteria and viruses.
- (ii) They are caused due to a lack of nutrients in our diet.
This statement accurately describes deficiency diseases. Conditions like scurvy (vitamin C deficiency) and rickets (vitamin D deficiency) arise from insufficient nutrients.
- (iii) They can be passed on to another person through contact.
This statement applies to infectious diseases, not deficiency diseases. Deficiency diseases are not contagious.
- (iv) They can be prevented by taking a balanced diet.
This statement is also correct for deficiency diseases. A balanced diet provides all necessary nutrients, preventing these diseases.
Conclusion
In summary, deficiency diseases are specifically linked to a lack of nutrients (statement ii) and can be prevented through a balanced diet (statement iv). Thus, the pair of statements that best describes a deficiency disease is option 'C' (ii and iv).
Understanding these distinctions helps us appreciate the importance of nutrition in maintaining good health!

  • Deficiency diseases occur when the body does not get enough of certain nutrients, like vitamins or minerals.
    • Example: Scurvy (lack of Vitamin C), Rickets (lack of Vitamin D).
  • They are not caused by germs and do not spread from one person to another (non-communicable).
  • They can be prevented and cured by eating a balanced diet that includes all essential nutrients.
Therefore, statements (ii) "caused due to a lack of nutrients" and (iv) "can be prevented by taking a balanced diet" correctly describe deficiency diseases.
