Hint: Various substances such as water, starch, proteins, etc. are processed by Parenchyma cells. They function as a reservoir of food and water and stored protein is a good source of nitrogen for plants as well. Parenchyma cells in succulent plants may be specialized as a water storage tissue.

Complete answer: Generally, parenchyma tissue is composed of living cells that are thin-walled, typical in shape, and thus appropriate in relation to different functions. The cells are present in plant bodies in many places and are actively involved in photosynthesis, secretion, food storage, and other plant life activities provided that they are alive. Parenchyma is a simple tissue composed of thin polyhedral walled, isodiametric cells with ample cytoplasm, and one or more nuclei. They perform in photosynthesis, storage, and as the bulk of soil and vascular tissues.
-But don't really offer the plant mechanical assistance and usually lack thickening of the cell wall, which is a characteristic property of mechanical tissues.
-The appearance of well-developed intercellular spaces identifies parenchymatous cells.
-Thin-walled cells with cellulose deposition and hemicellulose deposition are present in these tissues. Owing to the deposition of lignin, there is a lack of thick cell walls. These are cells with little to no intercellular spaces, compactly organized. There is a nucleus, there may be a vacuole present or missing, and there is cytoplasm in these cells.
Thus, choice C, i.e., the presence of a thick cell wall is the correct answer.

Note: The most common plant tissue with some unique characteristics is parenchyma. It is made of cells with intercellular spaces that are usually isodiametric in structure. Parenchyma cells are also able to convert to other types of cells and act as a precursor for other types of cells. These cells also have active protoplasts.
