b. Potassium	2. Essential constituent of chlorophyII
c. Calcium	3. Eessentia constituent of cell
d. Magnesium	4. Enhance drought and disease resistant power.

Solution(By Examveda Team)

a. Sulphur increases oil quality.
Sulphur application increases oil and protein contents in seeds. It also increases the availability of other nutrients such as phosphorus, potassium, and zinc and suppresses the uptake of sodium and chlorine which are toxic to plant growth and development.
b. Potassium enhances drought and disease-resistant power.
Potassium is associated with the movement of water, nutrients and carbohydrates in plant tissue. Under drought stress conditions, K regulates the stomatal opening and helps plants adapt to water deficits.
c. Calcium is an essential constituent of the cell.
Calcium is a constituent of the cell wall in the form of calcium pectate. It is required in small amounts for normal mitosis. Calcium is also involved in chromatin or mitotic spindle organization.
d. Magnesium is an essential constituent of chlorophyll.
The main constituent element of chlorophyll is Magnesium. Chlorophyll is the pigment found in the chloroplast. It is responsible for the green color of plants. The general formula of chlorophyll is C₅₅H₇₂O₅N₄Mg.
