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

Hint:

Whiptail of Cauliflower (Mo deficiency) and White bud of Maize (Zn deficiency) are highly recurrent questions.
Identifying either of these first will solve the entire match in seconds.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Micronutrient deficiencies in crops lead to distinct physiological disorders, which serve as diagnostic symptoms in field agronomy.

Step 2: Detailed Explanation:
Let us match the micronutrients with their associated physiological disorders:
Manganese (Mn) deficiency causes "Speckled yellow of Sugar beet", where leaves develop chlorotic spots between veins.
Thus, (A) matches with (I).
Molybdenum (Mo) deficiency is highly famous for causing "Whiptail of Cauliflower" due to restricted leaf lamina development.
Thus, (B) matches with (III).
Zinc (Zn) deficiency leads to "White bud of Maize", characterized by bleaching/chlorosis of the young unfolding leaves.
Thus, (C) matches with (II).
Copper (Cu) deficiency causes "Reclamation disease of Cereals", particularly on newly reclaimed organic soils, causing tip drying.
Thus, (D) matches with (IV).
Combining these: A-I, B-III, C-II, D-IV.

Step 3: Final Answer:
The correct matching is A-I, B-III, C-II, D-IV.
