Answer:
B. Membrane
Explanation:
Body membranes are thin sheets of tissue that cover the body, line body cavities, and cover organs within the cavities in hollow organs. They can be categorized into epithelial and connective tissue membrane.
Epithelial Membranes
Epithelial membranes consist of epithelial tissue and the connective tissue to which it is attached. The two main types of epithelial membranes are the mucous membranes and serous membranes.
Mucous Membranes
Mucous membranes are epithelial membranes that consist of epithelial tissue that is attached to an underlying loose connective tissue. These membranes, sometimes called mucosae, line the body cavities that open to the outside. The entire digestive tract is lined with mucous membranes. Other examples include the respiratory, excretory, and reproductive tracts.
Serous Membranes
Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium. Serous fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall. Serous membranes have special names given according to their location. For example, the serous membrane that lines the thoracic cavity and covers the lungs is called pleura.
Connective Tissue Membranes
Connective tissue membranes contain only connective tissue. Synovial membranes and meninges belong to this category.

The tissue layers are made of cell aggregates that have specific functions. The membrane is a structure composed of tissue layers that secrete fluids. Thus, option b is correct.
What is membrane tissue?
The membranes are the structural layers that are formed by the thin sheets of the tissues that line the body cavities and other organ systems. It includes epithelial, mucous, connective, and serous membranes.
The serious and the epithelial membranes secrete the fluid in the intracellular spaces and comprise the synovial membranes and fluids. These fluids are used for lubrication and to decrease the abrasion and friction in the cavity walls.
Therefore, option b. the membrane is the structures that have been composed of the tissues that have been secreting various fluids.
