Answer:

B) Cell

Explanation:

A cell is a structural entity that was formed during the primitive time which consists of the essential molecules and suitable conditions to perform the metabolic reaction needed to survive.

During the study of the plants and animal structure, Schleiden and Schwann found that they were composed of the almost same structure performing the same function.

They thus suggested that all the living organisms are composed of the cells and cell is the structural and functional unit of life.

Thus, Option-B is the correct answer.

As infection passes through these openings, it will affect the dermis and the other layers of the skin. Bullae is actually an auto-immune skin disease.
