Cockroaches are uricotelic organisms. The process of excretion in cockroaches is performed by Malpighian tubules, which are part of the insect's excretory system. These tubules are lined by glandular and ciliated cells, which absorb nitrogenous waste products and convert them into uric acid. This uric acid is then excreted out through the hindgut.

The nature of the nitrogenous waste excreted can be species-specific and is often influenced by the organism's environment and water availability. For instance, many bony fishes, aquatic amphibians, and aquatic insects, which have abundant access to water, are ammonotelic and excrete waste in the form of ammonia. In contrast, mammals, many terrestrial amphibians, and marine fishes, which live in environments where water conservation is critical, are ureotelic and excrete waste in the form of urea.

Given these details, the correct answer to the question "The Cockroach is:" would be Option B : Uricotelic only.
