B) H+, ATP and NADPH
C) O2, ATP and NADPH
D) ATP and NADPH
TELL THE REASON PLEASE​

Answer 1

Answer:

What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose

Answer 2

Initiation of light reactions : Light :: Initiation of dark reactions : D) ATP and NADPH

The light reactions are commenced by the presence of light. Chlorophyll absorbs the sunlight and converts light energy into chemical energy. This energy helps in further reactions.

Similarly, the dark reactions are commenced by the products of the light reaction- ATP and NADPH. The energy required for the reaction is taken from ATP and NADPH.

Thus, on the basis of sources of energy for the reactions, this question can be answered.
