Oxidative phosphorylation and photophosphorylation both require the electron carrier

Which of the following is the most abundant protein in the chloroplast?

$P$: During the dark reaction of photosynthesis,ketotriose is synthesized.
$Q$: The sugar present in the structure of $ATP$ is an example of a ketopentose sugar.

Consider the following statements.
$I.$ The portion of the spectrum between $300-500 \;nm$ is also referred to as Photosynthetically Active Radiation $(PAR)$.
$II.$ Magnesium,calcium and chloride ions play prominent roles in the photolysis of water.
$III.$ In cyclic photophosphorylation,oxygen is not released (as there is no photolysis of water) and $NADPH$ is also not produced.

Which of the following methods is responsible for $ATP$ production by green plant cells in the presence of sunlight?
