Solution

The correct option is A Urea
If a person takes large amount of proteins in his diet. He will excrete more of urea. The proteins in the diet undergoes deamination. During deamination the amino group is removed from the amino acid and converted to ammonia by urea cycle.

Urea is an excretory compound produced from nitrogenous wastes. The nitrogen in proteins produces ammonia, which is converted into urea in the liver in the urea cycle.

Uric acid is a waste product found in blood. It's created when the body breaks down chemicals called purines. Most uric acid dissolves in the blood, passes through the kidneys and leaves the body in urine. Food and drinks high in purines also increase the level of uric acid.

Once the blood sugar level gets higher than 180 mg/dl, the kidneys start to spill sugar into the urine. The higher the blood sugar, the more sugar comes out in the urine. If our kidneys are normal, this usually isn't a problem, but if we have diabetes, too much sugar can cause kidney damage.

So, in this given condition when a person takes large amount of proteins, he will excrete more amount of urea.
