For photosynthesis (i.e. for the synthesis of organic matter),the green plants need only

Photosynthesis takes place in:

Assertion: Six molecules of $CO_2$ and twelve molecules of $NADPH + H^+$ and $18\, ATP$ are used to form one hexose molecule.
Reason: Light reaction results in the formation of $ATP$ and $NADPH_2$.

Read the following four statements ($a, b, c,$ and $d$) carefully and select the option that includes both correct statements.
$(A)$ The $Z$-scheme of light reaction occurs only in the presence of $PSI$.
$(B)$ Only $PSI$ is functional in cyclic photophosphorylation.
$(C)$ Cyclic photophosphorylation results in the synthesis of $ATP$ and $NADPH_2$.
$(D)$ Stroma lamellae lack both $PS-II$ and $NADP$ reductase $(FNR)$.

Which of the following may show photosynthesis in moonlight?

Assertion : Dark reaction occurs only at night in the stroma of chloroplast.
Reason : $CO_2$ fixation occurs only during $C_3$ cycle.
