The correct answer is (c), Amla.
Amla is a small, round fruit that is native to India. It is also known as Indian gooseberry or amla berry. Amla is a good source of vitamins C, A, and E, as well as minerals such as iron, calcium, and potassium. It is also a good source of fiber.
Apples are a good source of fiber and vitamin C. They also contain small amounts of other vitamins and minerals.
Mangoes are a good source of vitamins A and C. They also contain small amounts of other vitamins and minerals.
Milk is a good source of protein, calcium, and vitamin D. It also contains small amounts of other vitamins and minerals.
Here is a table showing the vitamin C content of 100 grams of each of the four foods:
| Food | Vitamin C content (mg) |
|—|—|
| Apple | 10 |
| Mango | 30 |
| Amla | 176 |
| Milk | 1 |
As you can see, amla has the highest vitamin C content of the four foods.
