Which one of the following organisms does not evolve oxygen during photosynthesis?

Which one does not differ between a $C_3$ and a $C_4$ plant?
$I.$ Initial $CO_2$ acceptor.
$II.$ Extent of photorespiration.
$III.$ Enzyme catalyzing reaction that fixes $CO_2$.
$IV.$ Presence of Calvin cycle.
$V.$ Leaf anatomy.

During daylight hours,the rate of photosynthesis is higher than that of respiration,and the ratio of oxygen produced to that of consumed is (in $:1$)

Chemosynthesis and photosynthesis are alike in that both

If a green plant is kept in the dark with proper ventilation,can this plant carry out photosynthesis? Can anything be given as a supplement to maintain its growth or survival?
