(D) In some succulent plants,such as $Opuntia$,carbohydrates are incompletely oxidized to organic acids during the night (dark) without the release of $CO_2$.The chemical reaction is: $2C_6H_{12}O_6 + 3O_2 ightarrow 3C_4H_6O_5 + 3H_2O$.Since $CO_2$ is not evolved during this process,the Respiratory Quotient $(R.Q.)$ is calculated as:$R.Q. = \frac{	ext{Volume of } CO_2 	ext{ evolved}}{	ext{Volume of } O_2 	ext{ consumed}} = \frac{0}{3} = 0$.

In $Opuntia$,at night the $R.Q.$ will be
