(D) The balanced chemical equation for photosynthesis is: $6CO_2 + 6H_2O \xrightarrow{	ext{Chlorophyll, Sunlight}} C_6H_{12}O_6 + 6O_2$.From the equation,$1$ mole of glucose $(C_6H_{12}O_6)$ is produced from $6$ moles of water $(H_2O)$.The molar mass of glucose is $(6 	imes 12) + (12 	imes 1) + (6 	imes 16) = 72 + 12 + 96 = 180\, g/mol$.The molar mass of water is $(2 	imes 1) + 16 = 18\, g/mol$.Thus,$180\, g$ of glucose requires $6 	imes 18 = 108\, g$ of water.Therefore,$18\, g$ of glucose requires: $\frac{108}{180} 	imes 18 = 10.8\, g$ of water.Given the density of water is $1\, g\, cm^{-3}$,the volume of water consumed is: $	ext{Volume} = \frac{	ext{Mass}}{	ext{Density}} = \frac{10.8\, g}{1\, g\, cm^{-3}} = 10.8\, cm^3$.
