Answer: B. Platyhelminthes and AnnelidaSolenocytes:- Found in Platyhelminthes (flatworms)- Also called protonephridia or flame cells- Tubular structures with a ciliated flame bulb at one end- Remove waste products from the body and maintain osmoregulation- Flame bulb filters waste from the body fluid and cilia propel it through the tubules, eventually excreting waste through excretory poreMetanephridia:- Found in Annelida (segmented worms)- Excretory organs consisting of a ciliated funnel, a tubule, and a nephridiopore- Present in each segment of the body- Ciliated funnel collects waste from the coelomic fluid- Tubule modifies the filtrate and reabsorbs useful substances- Nephridiopore expels the waste outside the body- Also helps in osmoregulationIn summary, solenocytes are found in Platyhelminthes, while metanephridia are found in Annelida. Both of these excretory organs serve to remove waste products from the organisms and help maintain osmoregulation.

Excretory Organs of Platyhelminthes and Annelida
Platyhelminthes and Annelida are two different phyla of the animal kingdom, each with its own unique excretory organs. In Platyhelminthes, the excretory system consists of flame cells, while in Annelida, solenocytes and metanephridia are the main excretory organs.
Solenocytes in Annelida
Solenocytes are specialized excretory cells found in the body wall of annelids. These cells are responsible for removing metabolic wastes from the coelomic fluid and releasing them into the excretory system for elimination. Solenocytes play a crucial role in maintaining the osmotic balance and overall homeostasis of the organism.
Metanephridia in Annelida
Metanephridia are segmentally arranged excretory organs in annelids that function in waste excretion and osmoregulation. Each metanephridium consists of a ciliated funnel-like structure called a nephrostome, a tubular excretory duct, and a bladder-like structure called a bladder. Metanephridia filter waste products from the coelomic fluid and eliminate them through an opening called a nephridiopore on the body surface.
Therefore, solenocytes and metanephridia are the excretory organs of Platyhelminthes and Annelida, respectively. These organs play essential roles in maintaining the internal environment of the organisms by removing waste products and regulating osmotic balance.
