Explanation:
As a seed germinates and a seedling grows into a young plant, the size of the seed leaves gradually becomes smaller because the food that seed leaves have, have been used by the growing plant. This process is explained in detail below:
1. Seed Leaves:
When a seed germinates, the first leaves that appear are called seed leaves. These leaves provide the initial nutrients and energy required by the young plant to grow. They are also known as cotyledons and are present in the embryo of the seed.
2. Nutrients:
The seed leaves store nutrients such as starch, proteins, and oils that are required by the young plant for growth. As the plant grows, it uses these stored nutrients to produce new leaves, stems, and roots.
3. Photosynthesis:
As the young plant grows, it starts producing its food through photosynthesis. During photosynthesis, the plant uses sunlight, carbon dioxide, and water to produce glucose and oxygen. This glucose is used as energy by the plant for growth and development.
4. Reduction in Seed Leaf Size:
As the young plant starts producing its food through photosynthesis, it starts relying less on the stored nutrients in the seed leaves. As a result, the size of the seed leaves gradually becomes smaller because the food that seed leaves have, have been used by the growing plant.
Conclusion:
In conclusion, the size of the seed leaves gradually becomes smaller as the young plant grows because the food that seed leaves have, have been used by the growing plant. As the plant starts producing its food through photosynthesis, it relies less on the stored nutrients in the seed leaves, and hence the size of the seed leaves reduces.

The correct answer is 'C'. The food that seed leaves have, have been used by the growing plant.
