The cells in epithelial tissue are densely packed, with little intercellular matrix. The cells have one free surface that is not in contact with other cells because the tissues form coverings and linings. A non-cellular basement membrane connects the cells to the underlying connective tissue opposite the free surface. This membrane is made up of carbohydrates and proteins.
This membrane is made up of carbohydrates and proteins that are secreted by epithelial and connective tissue cells. Epithelial cells can be squamous, cuboidal, or columnar in shape, and they can be organised in single or multiple layers.
Simple cuboidal epithelial tissue can be found in glandular tissue and kidney tubules. The stomach and intestines are lined with simple columnar epithelium. Pseudostratified columnar epithelium lines parts of the respiratory tract and some male reproductive tract tubes. Transitional epithelium can be stretched or distended. The glandular epithelium is specialised in the production and secretion of substances.
Squamous epithelium is an epithelial tissue composed of thin flat cells arranged edge to edge to resemble closely packed tiles. It protects moist surfaces that are subject to minimal friction wear and tear, such as the inner lining of the cheeks, the lining of blood vessels, the alveoli, and so on.

Therefore the correct answer is option (D) Inner lining of cheeks.

• The pharynx is a part of the digestive system which is the conducting zone of the respiratory system.
• The pharynx makes up the part of the throat situated immediately posterior to the nasal cavity, posterior to the mouth and superior to the esophagus and larynx.
• The pharynx is lined by non-keratinised squamous stratified epithelium also called as compound squamous epithelium.

Hence, the correct option is B.

• If the epithelium is composed of one layer of cells, it is referred to as simple squamous epithelium and if it possesses multiple layers, it is referred to as stratified squamous epithelium.
• The peritoneum is the serous membrane that forms the lining of the abdominal cavity or coelom. It covers most of the intra-abdominal (or coelomic) organs and is composed of a layer of mesothelium supported by a thin layer of connective tissue.  The mesothelium is a membrane composed of simple squamous cells that form the lining of several body cavities like peritoneum.

Hence the correct option is D.

• Cilia can be defined as the hair-like structures that sit on top of a tissue. They wave back and forth which help move things. 
• Ciliated epithelium performs the function of moving particles or fluid over the epithelial surface in such structures as the trachea, bronchial tubes, and nasal cavities. 
• A ciliated columnar epithelium lines the lumen of the uterine tube, where currents generated by the cilia propel the egg cell toward the uterus. They are also present in the buccal cavity of frog.

Hence, the correct option is A.

• Epithelial tissue has a free surface, which faces either a body fluid or the outside environment and thus provides a covering or a lining for some part of the body.
• The cells of this tissue are compactly packed with a little intercellular matrix.
• There are two types of epithelial tissues namely simple epithelium and compound epithelium.

Hence, the correct option is A
NCERT Reference: Page no. 101 of topic “7.1.1 Epithelial Tissue” of chapter 7.

A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.

• Simple epithelium tissue is one layer thick while stratified epithelium tissue is multi-layered.
• Stratified epithelia cover the exterior body surfaces and lining portions of the body tracts, where friction occurs. 
• A multilayered epithelium allows deeper cells to replace the most superficial cells, as they are damaged or cast off from the epithelial surface. 

So, the epidermis of skin in vertebrates comprises stratified epithelium. 
Hence, the correct option is B.
