Everything we eat and drink throughout the day is called our diet.<\/p><p>Option (B) is also correct. A balanced diet contains the right amounts of carbohydrates, proteins, fats, vitamins, minerals, roughage, and water according to the body&#8217;s requirements. None of these nutrients should be present in excess or deficiency.<\/p><p>Option (C) is also correct. If vegetables and fruits are washed after peeling, some water-soluble vitamins, especially Vitamin B and Vitamin C, as well as certain minerals, may be lost. Therefore, fruits and vegetables should generally be washed thoroughly before peeling.<\/p><p>A balanced diet is essential for proper growth, development, disease resistance, and overall health.

Vitamin C<\/div><div class=\"option\">D. Vitamin D<\/div><button class=\"answer-btn\">Answer<\/button><div class=\"solution\"><p><b>Answer:<\/b> C<\/p><p>The correct answer is Vitamin C.<\/p><p>Vitamin C is highly sensitive to heat.

Vitamins are essential micronutrients required in very small amounts, but they play an important role in normal growth, development, immunity, and various body functions. A prolonged deficiency of any vitamin can lead to specific diseases.<\/p><p>The main function of Vitamin A is to maintain normal vision, healthy skin, and immunity. Its deficiency causes dim vision, especially night blindness. Severe deficiency may also damage the cornea and increase the risk of permanent vision loss. Therefore, Vitamin A \u2192 Dim vision (1-a) is correct.<\/p><p>Vitamin B\u2081 (Thiamine) is essential for releasing energy from food and for the normal functioning of the nervous system and muscles. Its deficiency causes beriberi, which leads to muscle weakness, fatigue, difficulty in walking, and nervous disorders. Hence, Vitamin B\u2081 \u2192 Beriberi (2-c) is correct.<\/p><p>Vitamin C plays an important role in strengthening immunity, healing wounds, and maintaining healthy gums. Its deficiency causes scurvy, characterized by bleeding gums, delayed wound healing, weakness, and skin problems.

Daily activities such as walking, running, studying, and even thinking depend mainly on the energy obtained from carbohydrates. Wheat, rice, maize, millet, potatoes, and sugar are their major sources. Therefore, Carbohydrates \u2192 Provide energy (1-c) is correct.<\/p><p>Proteins are known as body-building nutrients. They help in the formation of new cells, repair damaged tissues, and support the growth of children and adolescents. Pulses, milk, eggs, fish, meat, and soybeans are major sources of protein. Hence, Proteins \u2192 Growth and repair of body tissues (2-a) is correct.<\/p><p>Fats are a concentrated source of energy and also store excess energy for future use. They help protect internal organs and keep the body warm. Therefore, Fats \u2192 Stored source of energy (3-d) is correct.<\/p><p>Vitamins do not provide energy. Instead, they regulate various biological functions and help protect the body against diseases.

Dietary fibre (roughage) does not provide energy or nutrients to the body, but it increases the bulk of food, keeps the digestive system healthy, and helps prevent constipation. It also supports the normal functioning of the large intestine.<\/p><p>Statement 2 is correct. Water is an essential component of the body.
