Step 1: Understanding ascorbic acid.
Ascorbic acid is Vitamin C, an essential nutrient that acts as an antioxidant and boosts immunity. Fruits like guava, citrus, and amla (Aonla) are rich in Vitamin C.
Step 2: Compare the given fruits.
- Winter guava: Rich in Vitamin C, but not the highest. Contains about 200 mg/100 g.
- Acid lime: Citrus fruit, also a good source, around 50 mg/100 g.
- Sweet orange: Contains moderate Vitamin C, around 40–60 mg/100 g.
- Aonla (Indian gooseberry): Exceptionally rich source, contains 600–900 mg/100 g, the richest among commonly available fruits.
Step 3: Conclusion.
Thus, Aonla is the richest source of ascorbic acid among the given fruits.
Final Answer: \[ \boxed{\text{Aonla is the richest source of ascorbic acid (Vitamin C).}} \]
