(2) (A) - (Il), (B) - (Ill), (C) - (IV), (B) - (1) - Copper (A) → Ascorbic acid oxidase & polyphenol oxidase (II): Copper acts as an essential prosthetic metal ion in cuproenzymes including plastocyanin, cytochrome c oxidase, ascorbic acid oxidase, and polyphenol oxidase involved in terminal redox cascades. - Iron (B) → Catalase & peroxidase (III): Iron functions as the central heme metallic cofactor in hemoprotein enzymes such as catalase and peroxidase that decompose toxic peroxides in plant cells. - Zinc (C) → Carbonic anhydrase & alcohol dehydrogenase (IV): Zinc is mandatory for the catalytic activity of carbonic anhydrase (interconverting CO₂ and HCO₃⁻) and alcohol dehydrogenase in plant root respiration. - Molybdenum (D) → Nitrogenase & nitrate reductase (I): Molybdenum forms the FeMo-cofactor in nitrogenase (catalyzing symbiotic N₂ fixation) and the molybdopterin cofactor in nitrate reductase. - Conclusion: (A)-(II), (B)-(III), (C)-(IV), (D)-(I). (Correct answer: Option 2)

Match List-I with List-II:

Choose the correct answer from the options given below:

List - I Nutrient element		List - II Enzymes
A	Copper Copper	I	Nitrogenase and nitrate reductase Nitrogenase and nitrate reductase
B	Iron Iron	II	Ascorbic acid oxidase and polyphenol oxidase Ascorbic acid oxidase and polyphenol oxidase
C	Zinc Zinc	III	Catalase and peroxidase Catalase and peroxidase
D	Molybdenum Molybdenum	IV	Carbonic anhydrase and alcohol dehydrogenase Carbonic anhydrase and alcohol dehydrogenase

(A) - (1), (B) - (Il), (C) - (Ill), (D) - (IV) (A) - (Il), (B) - (Ill), (C) - (IV), (B) - (1) Correct (A) - (1), (B) - (M), (C) - (V), (D) - (ttl) (A) - (III), (B) - (V), (C)~ (1), (B) - (HN)

Copper (A) $\rightarrow$ Ascorbic acid oxidase & polyphenol oxidase (II): Copper acts as an essential prosthetic metal ion in cuproenzymes including plastocyanin, cytochrome c oxidase, ascorbic acid oxidase, and polyphenol oxidase involved in terminal redox cascades.
Iron (B) $\rightarrow$ Catalase & peroxidase (III): Iron functions as the central heme metallic cofactor in hemoprotein enzymes such as catalase and peroxidase that decompose toxic peroxides in plant cells.
Zinc (C) $\rightarrow$ Carbonic anhydrase & alcohol dehydrogenase (IV): Zinc is mandatory for the catalytic activity of carbonic anhydrase (interconverting $CO_2$ and $HCO_3^-$) and alcohol dehydrogenase in plant root respiration.
Molybdenum (D) $\rightarrow$ Nitrogenase & nitrate reductase (I): Molybdenum forms the FeMo-cofactor in nitrogenase (catalyzing symbiotic $N_2$ fixation) and the molybdopterin cofactor in nitrate reductase.
Conclusion: (A)-(II), (B)-(III), (C)-(IV), (D)-(I). (Correct answer: Option 2)
