Highest amount of vit. C is found in
**Core Concept**
Vitamin C, also known as ascorbic acid, is an essential water-soluble vitamin that plays a crucial role in various bodily functions, including collagen synthesis, iron absorption, and immune function. It is also known for its antioxidant properties.
**Why the Correct Answer is Right**
Vitamin C is primarily found in citrus fruits, and among them, **oranges** are one of the richest sources of this essential nutrient. The high concentration of vitamin C in oranges is due to the presence of the enzyme _dehydroascorbic acid reductase_, which is responsible for the regeneration of ascorbic acid from its oxidized form. This enzyme is present in high amounts in oranges, making them an excellent source of vitamin C.
**Why Each Wrong Option is Incorrect**
**Option A:** **Grapes** are a good source of vitamin C, but not as rich as oranges. Grapes contain a lower amount of ascorbic acid compared to oranges.
**Option B:** **Strawberries** are another fruit that contains vitamin C, but their concentration is lower than that of oranges. Strawberries are a good source of vitamin C, but not the richest source.
**Option C:** **Pineapples** are a tropical fruit that contains vitamin C, but again, their concentration is lower than that of oranges. Pineapples are a good source of vitamin C, but not the highest among fruits.
**Clinical Pearl / High-Yield Fact**
A diet rich in vitamin C can help prevent scurvy, a disease caused by a deficiency of this essential nutrient. Scurvy is characterized by fatigue, weakness, and bleeding gums, and can be prevented by consuming foods rich in vitamin C, such as oranges, citrus fruits, and leafy green vegetables.
**Correct Answer:** A. Oranges
