The sebaceous gland is lined with a cuboidal stratified epithelium, that has continuity with external root sheath of hair follicle. The epithelium of sebaceous gland is modified and along it's base is a row of cuboidal cells

The correct answer is option 'A': Cuboidal stratified epithelium.
Explanation:
The sebaceous ducts are part of the sebaceous glands, which are responsible for producing and secreting sebum, an oily substance that helps lubricate and protect the skin. The lining of the sebaceous ducts is composed of cuboidal stratified epithelium.
- The sebaceous glands are found in the dermis of the skin and are connected to hair follicles. They are most abundant on the face and scalp but can be found throughout the body.
- The sebaceous ducts are the channels that connect the sebaceous glands to the hair follicles or to the surface of the skin. They allow sebum to be transported to the skin surface or to coat the hair shaft.
- The lining of the sebaceous ducts is formed by layers of cuboidal epithelial cells. Cuboidal epithelium consists of cells that are roughly cube-shaped, with their height, width, and depth being approximately equal.
- Stratified epithelium refers to epithelial tissue that is composed of multiple layers of cells. In the case of the sebaceous ducts, the stratified epithelium is cuboidal, meaning that the cells are cube-shaped.
- The presence of stratified epithelium in the lining of the sebaceous ducts is important because it allows for the production and secretion of sebum. The multiple layers of cells provide a larger surface area for sebum production and help to prevent the ducts from becoming clogged.
In summary, the lining of the sebaceous ducts is composed of cuboidal stratified epithelium. This type of epithelium allows for the production and secretion of sebum, which helps to lubricate and protect the skin.
