Option 4, Sclerenchyma, is the correct answer. Sclerenchyma is a type of plant tissue that consists of dead cells. These cells have thick, lignified cell walls which provide support and protection to the plant. The dead cells of sclerenchyma tissue are characterized by their hard and rigid structure, making this tissue type particularly useful in plant parts that require strength and durability.

Option 1, Epidermis, is incorrect. Epidermis is the outermost layer of cells in plants and it is typically composed of living cells that play a role in protection and gas exchange.

Option 2, Parenchyma, is also incorrect. Parenchyma is a type of plant tissue that consists of living cells, often with thin cell walls. It is responsible for various functions, such as photosynthesis, storage, and secretion.

Option 3, Collenchyma, is another incorrect choice. Collenchyma is a type of plant tissue that consists of living cells with unevenly thickened cell walls. It provides support to growing parts of the plant, but the cells are not dead like in sclerenchyma tissue.

Therefore, the correct answer is option 4, Sclerenchym
