Compare and contrast the types of nitrogenous wastes excreted

I don't think this is a multiple choice question.

Ammonia is the most toxic and must be diluted with large amounts of water to be excreted safely. Urea and Uric Acid are less toxic and do not have to be excreted with large amounts of water, but requires more energy expenditure to produce. Uric acid can be excreted with the least amount of water.

Bony fishes excrete ammonia; mammals excrete urea; and insects excrete uric acid. You would expect the embryos inside terrestrial eggs to produce uric acid, since it's the least toxic and has very low solubility in water.
