In $C_3$ plants,the first stable product of the Calvin cycle is:

In $C_{3}$ plants, the first stable product of photosynthesis during dark reaction is

$3 CO_{2} + 9 ATP + 6 NADPH + \text{water} \rightarrow \text{glyceraldehyde 3-phosphate} + 9 ADP + 6 NADP^{+} + 8 \Pi$. Analyse the above reaction and answer the following questions:
$(a)$ How many molecules of $ATP$ and $NADPH$ are required to fix one molecule of $CO_{2}$?
$(b)$ Where in the chloroplast does this process occur?

In the $C_3$ pathway,the first stable product is $P$,and in the $C_4$ pathway,the first stable product is $Q$. Choose the correct option for $P$ and $Q$.
