The table shows vitamins that should be included in a balanced diet. Which row shows the correct use in the body and food source for one of these vitamins?
▶️ Answer/Explanation
Ans: C
Vitamin C is essential for healthy skin and wound healing and is commonly found in citrus fruits (e.g., oranges).
Option C correctly matches Vitamin C with its function (preventing scurvy and aiding tissue repair) and its food source (oranges). Other options contain inaccuracies:
- A (Vitamin D) is incorrect because its primary source is sunlight, not just dairy.
- B (Vitamin A) is incorrect because carrots (not just liver) are a key source.
- D (Vitamin B) is incorrect because whole grains (not just meat) provide B vitamins.
Thus, the correct answer is C.
The pie charts show the composition of 100 g of four different foods. Which food provides the most energy?
▶️ Answer/Explanation
Ans: B
Energy is primarily derived from fats (highest energy/gram), followed by carbohydrates and proteins. Water contributes no energy.
Food B has the lowest water content and a balanced distribution of fats, carbohydrates, and proteins, maximizing energy per 100 g. In contrast, Foods C and D have high water content, diluting their energy density despite some fat content.
Thus, B provides the most energy.
