Answer 1

Hill reaction occurs in
A) High altitude plants

Answer 2

"Hill reaction" occurs in "Presence of ferredoxin".

Option - D

Explanation:

• Hill reaction is the light phase or photochemical phase of photosynthesis which consists of light driven splitting of water or photolysis, evolution of oxygen and synthesis of assimilatory power (AIP and NADPH).
• An enzyme complex, Mn, Cl and ferricyanides are required for this reaction.
• Ferredoxin (Fd) is found in chloroplasts which mediates electron transfer and contains an iron-sulfur cluster $([Fe_{4}S_{4}(SME)_{4}]^{2-})$.

• It is involved in the photosynthesis process where its iron atoms accept or discharge electrons when they are being oxidized or reduced.
