• C. A-II, B-IV, C-I, D-III
• D. A-III, B-II, C-I, D-IV

Answer 1

The Correct Option is B

A. Iron - III. Activator of catalase 
B. Zinc - I. Synthesis of auxin 
C. Boron - IV. Cell elongation and differentiation 
D. Molybdenum - II. Component of nitrate reductase

Therefore, The correct option is (B): A-III, B-I, C-IV, D-II

Answer 2

Explanation:

1. Iron: Iron is involved in the synthesis of chlorophyll, and in the activation of catalase. Catalase is an enzyme that contains four iron heme groups allowing it to react with hydrogen peroxide.
2. Zinc: It is required for the synthesis of auxin. Auxin is a plant growth hormone that help stimulate cell elongation in stems.
