Match List-I with List-II:

List-I (Elements)	List-II (Functions in Plants)
(A) Iron	(I) Chlorophyll biosynthesis
(B) Zinc	(II) Photolysis of water
(C) Manganese	(III) Indole Acetic Acid biosynthesis
(D) Boron	(IV) Translocation of sugars

Choose the correct answer from the options given below:

Correct option is B

The correct answer is (B) (A)-(I), (B)-(III), (C)-(II), (D)-(IV)

Explanation:
• Iron (A): Essential for the synthesis of chlorophyll (I), although it is not a part of the chlorophyll molecule itself (Magnesium is the central atom).
• Zinc (B): Required for the biosynthesis of Indole Acetic Acid (III), which is a natural auxin (plant hormone). Zinc deficiency leads to 'little leaf' disease.
• Manganese (C): Plays a critical role in the photolysis of water (II) during the light reaction of photosynthesis (Oxygen Evolving Complex).
• Boron (D): Essential for the translocation of sugars (IV) through the phloem by forming sugar-borate complexes.

Information Booster:
• Boron is also critical for pollen germination and cell differentiation.
• Manganese deficiency often causes 'Grey speck' in oats.
• Iron is a constituent of ferredoxin and cytochromes.

Additional Knowledge:
• Option A, C, and D provide incorrect functional pairings. For instance, Zinc is not involved in water photolysis, and Boron is not the primary element for chlorophyll synthesis. Understanding these specific physiological roles is a core part of agricultural science.
