B. Ap, Br, Cs, Dq
C. Ar, Bs, Cp, Dq
D. As, Bq, Cr, Dp

Answer

D

Explanation

* Emerson effect – Carried out flashing light experiments at different temperature and showed the existence of light and dark reaction.
* Hill reaction – Proposed Z scheme and photolysis of `H_2O` Calvin cycle – Use choleralla as an experimental material discovered first stable product of photosynthesis, traces the path of carbon using `""^(14)CO_2` in photosynthesis i.e. Calvin cycle `(C_3)`.
* Hatch and slack pathway – Traced `C_4` cycle for `CO_2` fixation in certain tropical grasses.
