Nataliya [291]

Answer:

Eggs

Explanation:

Uric acid stones are one of the four types of kidney stones which are formed due to the high amount of uric acid in the human body.

To remove the uric acid kidney-stones, the food rich in purines must be avoided like meat, eggs and green vegetables like mustard, spinach, and whole grains are suggested.

Thus, the egg is the correct answer.
