A plant cell usually contains a single large sap vacuole. They surround cell sap or water or vacuolar fluid with dissolved inorganic and organic substances. It is separated from cytoplasm by a selectively permeable membrane called tonoplast.

Complete answer:
The cell sap is considered as a non-living content of the vacuole. Cell sap is the sap or fluid manufactured by the cytoplasm of the living plant cell. Cell sap contains mineral salts, sugars, amino acids, proteins, waste products and water soluble pigments like anthocyanins (red, blue, purple) and anthoxanthins (ivory to deep yellow). They provide colouration to flowers in rose, dahlia, etc. The pigments attract pollinating and dispersing agencies. They are also able to absorb light radiations passing through them so that their intensity is decreased. Cell sap contains about twice the viscosity of water. The cell sap plays a significant role in osmotic properties and turgor of the cell, and consequently, to the elasticity of plant tissues and organs. They can also store various useful as well as waste orgastic substances. Some plant vacuoles have special transport proteins, an acidic pH, a battery of hydrolytic enzymes and function as lysosomes. Plant vacuole along with the cell inclusions is considered as the non-living component of the cell.

So, the correct answer is option A.

Note: Cell sap is the fluid present inside the large sap vacuoles of the plant cell. It comprises salts, sugars, amino acids and mainly water. It provides buoyancy and support to the cell. It also helps in storage of many materials. Cell sap maintains osmosis of the cell. It also helps in colouration due dissolved pigments in it.
