B) Colour blindness
C) Kwashiorkor disease
D) Marasmus disease

Answer 1

Hint: A well-balanced diet is critical to a person's overall health. Any dietary imbalance may result in an excess or inadequate intake of certain nutrients. A deficiency disease may result from a lack of a specific nutrient. Deficiency diseases are illnesses that are caused by a long-term lack of certain essential nutrients, especially vitamins and minerals, in one's diet.

Complete answer:
Now let us look into the given options:
Option A) Night blindness – is the correct answer because it is a deficiency disease caused due to the deficiency of Vitamin A. Night blindness can be cured by incorporating vitamin A-rich foods in one's diet, such as yellow fruits (such as papaya), carrots, and butter.
Option B) Colour blindness – is an incorrect answer as it is a genetic disorder in which a person is unable to differentiate between different shades of colour.
Option C) Kwashiorkor disease - is an incorrect answer because Kwashiorkor is a disorder caused by a lack of protein in the diet.
Option D) Marasmus disease - is an incorrect answer because Marasmus is a form of malnutrition that affects children. It can affect anyone who is severely malnourished, but it is more common in children.

Hence, the correct answer is Night blindness i.e, option ‘A’.

Note: Food that has been cooked for an extended period or that has been undercooked will lose its nutritional value. Cutting vegetables and fruits and storing them for prolonged periods loses their nutritional value. By avoiding this we can prevent deficiency diseases.
