• D. (a)- (iii); (b) - (i); (c) - (ii);(d) - (iv)

Answer 1

The Correct Option is B

• Manganese plays a crucial role in the photosynthesis process by enabling the splitting of water molecules, following the initiation of CO₂ and water conversion into carbohydrates through Photosystem II (PSII) and light absorption.
• Magnesium, on the other hand, is involved in the activation of enzymes for both respiration and photosynthesis, as well as contributing to DNA and RNA synthesis.
• Boron is an essential nutrient for pollen germination and growth of pollen tubes.
• Finally, iron serves as an activator for catalase, an enzyme that contains four iron heme groups that allow it to effectively react with hydrogen peroxide.
