B, C and D only

Explanation:

Excretion in cockroaches involves several specialised components:

• Ureteral glands: These organs directly eliminate waste from the body.
• Nephrocytes: Located in the Malpighian tubules, these cells are vital for filtering out nitrogenous waste.
• Fat bodies: While not primary excretory organs, they assist by storing and processing metabolic waste products.
