Fordyce’s spot involves –
**Core Concept**
Fordyce's spots are small, yellowish or whitish bumps on the skin, typically found on the lips, inside of the cheeks, and sometimes on the genital area. They are a result of the abnormal presence of sebaceous glands in the mucosa, which is not a typical location for these glands.
**Why the Correct Answer is Right**
Fordyce's spots are formed when the sebaceous glands become ectopically located in the mucosa, leading to their abnormal presence. These glands produce sebum, which is a mixture of lipids that help to lubricate the skin and mucous membranes. In the case of Fordyce's spots, the sebum is produced in the mucosa, causing the formation of these small bumps. The ectopic sebaceous glands are usually found in areas where there is a high concentration of mucous membranes, such as the lips and genital area.
**Why Each Wrong Option is Incorrect**

**Correct Answer: D. Fordyce's spots are formed when the sebaceous glands become ectopically located in the mucosa, leading to the abnormal presence of these glands in areas where they are not typically found.
