The Correct Option is C
Solution and Explanation
Sponging mouthparts are found in the housefly and some other flies to suck up the liquefied food. These flies lack the cutting weapons of the insects that chew the food. They comprise a fleshy and retractile proboscis (formed by labium) consisting of three parts - rostrum, bearing the maxillary palps; haustellum with a middorsal groove, serving as food passage and a ventral heart shaped plate called theca and labellum underside of which is made of numerous incomplete cylindrical tubes the pseudotracheae. Labellum is used to lick the food by its contractile activity. It is first collected into the pseudotracheae and then passed on to the food canal.

Structural Organisation of Different Organs and Organ Systems
The structural organization of different organs can be categorized into tissue systems and organ systems.
Tissue Systems:
The biological definition of tissue places it in-between the cells and organs in the organizational level of the cell. Thus, tissues are the in-between stage of cells and complete organs and organ systems. A tissue is a collection of cells and their extracellular matrix arising from the same origins to carry out a specific function.
Organ Systems:
An organ system is formed by two or more organs that work together to perform and execute a specific function. This organ system is also known as the biological system or the body system.
