Hint: There exists a principle contrast in the middle of parenchyma collenchyma and sclerenchyma. That is, the parenchyma cells are associated with photosynthesis, stockpiling, and emission. However, the collenchyma cells are associated with the help and transportation of supplements. Besides, the sclerenchyma cells are engaged with the support, insurance, and transportation of water.

Complete answer: Suberin is found in the phellem layer of the periderm (or plug). Suberin functions as a physical hindrance, forestalling water loss from the tissues it encompasses just as giving insurance against microbes. It additionally shapes a considerable part of the injury recuperating measure in plants.
When sclerenchyma tissue is matured, it is made out of dead cells with intensely thickened dividers containing lignin and high cellulose content (60%–80%) and serve the capacity to offer necessary help in plants. Sclerenchyma cells have two sorts of cell dividers: essential and optional dividers.
Collenchyma cells are prolonged cells with sporadically thick cell dividers that offer help and structure. Their thick cell dividers are made out of the compound cellulose and pectin. These cells are regularly found under the epidermis or the external layer of cells in young stems and leaf veins.
Cutin and waxes are greasy substances kept in the epidermal cells' dividers, framing a waterproof external layer called the fingernail skin. Cutin is the significant segment of the fingernail skin, the waxy, water-repulsing surface layer of cell dividers presented to the climate over-the-ground.
Hence, Option (A) A-4, B-1, C-2, D-3 is the correct answer.

Note: Suberin, which is found in the phellem layer of the periderm, is a peripheral layer of the bark. The cells in this layer are dead and plentiful in suberin, forestalling water loss from the tissues beneath. Developed sclerenchyma cells are dead cells that have intensely thickened dividers containing lignin. Such cells happen in a wide range of shapes and sizes; however, two principal types happen, filaments and sclereids. The collenchyma cell divider is made out of an essential divider composed of cellulose, and at specific spots, it is stored inside an auxiliary divider composed of hemicellulose or gelatin. In some higher plants, the fingernail skin is a water-impenetrable defensive layer covering the epidermal cells of leaves and different parts and restricting water loss.
