Correct option: D.
Lungs

Explanation:
Nitrogenous waste products are generated during the breakdown of proteins by the cells as they catabolize amino acids to obtain energy. During the process of delamination, enzymes remove the amino group as ammonia which is highly toxic even in small quantities. In humans, this is combined with carbon dioxide to give urea and uric acid, which is thrown out by the function of the kidneys in the form of urine.
