• A. a - V - v, b - III - iv, c - II - iii, d - I - ii, e - IV - i
• B. a - I - iv, b - II - v, c - III - iii, d - IV - i, e - V - ii
• C. a - V - v, b - IV - iv, c - III - i, d - II - iii, e - I - ii
• D. a - IV - iii, b - I - iv, C - V - v, d - III - ii, e - II - i

Answer 1

The correct option is A a - V - v, b - III - iv, c - II - iii, d - I - ii, e - IV - i

a) Calcium - It is required for synthesis of the cell wall, mitotic spindle and organisation of chromosome. Due to its deficiency, young tips begin to die.

b) Boron - It is required for uptake and utilisation of Ca++. It's deficiency cause death of meristem and reduced fertility in the plant.

c) Phosphorus - It is a constituent of the cell membrane, proteins, nucleotides, nucleic acids, ATP and nucleoproteins in the plant. Its deficiency can cause red blot leaves.

d) Chlorine - It is required for anion-cation balance in plants. It's deficiency cause wilting and chlorosis.

e) Manganese - It is required to activate respiratory enzymes. Its deficiency can cause grey blot in the plant.

So the correct answer is 'a-V-v, b-III-iv, c-II-iii, d-I-ii, e-IV-i'.
