The NCERT line that answers it
Verbatim line**Figure 11.8** The Calvin cycle proceeds in three stages : (1) carboxylation, during which $\text{CO}_2$ combines with ribulose-1,5-bisphosphate; (2) reduction, during which carbohydrate is formed at the expense of the photochemically made ATP and NADPH; and (3) regeneration during which the $\text{CO}_2$ acceptor ribulose-1,5-bisphosphate is formed again so that the cycle continues

- Photosynthesis in Higher Plants
- Section
- 11.7 WHERE ARE THE ATP AND NADPH USED?
The answer appears as a continuous sentence in NCERT. This is that sentence.
How this line gives the answer
8, emb=0.9598, combined=0.8959). Verified: high — The span explicitly states that the reduction stage of the Calvin cycle (dark reaction) uses 'ATP and NADPH' and that carboxylation involves CO₂, directly matching the correct answer C (CO₂, ATP, NADPH) while excluding light and chlorophyll.
We did this for 1,565 questions.
Every one traced to the exact sentence in NCERT that answers it, including 90% of the 2026 paper. Sit a mock on the real NEET 2027 computer interface and every mark you drop comes back with its line attached.
