Correct answer
D. Uricotelic only
Step-by-step solution
Option (4) is the correct answer because in cockroach excretion is performed by Malpighian tubules. Each tubule is lined by glandular and ciliated cells. They absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut. Therefore, they are called uricotelic. - Many bony fishes, aquatic amphibians and aquatic insects are ammonotelic in nature. - Mammals, many terrestrial amphibians and marine fishes are ureotelic in nature.
