a scientist discovers a new organism in the ocean. the scientist thinks the organism excretes nitrogen waste as urea. Which of the following justifies this piece of information.

a) urea is excreted by all aquatic animals
b) urea is a highly toxic form of nitrogen excretion, and the abundance of water in the ocean is sufficient to dilute the the toxicity to safe levels.
c)urea is insoluble, and so seperates out from the water, preventing water toxicty
d) urea requires a little water for removal, and water retention is critical to survival in saltwater environments.
