A
Potassium
B
Magnesium
C
Nitrates
D
Iron
Explanation: 

Detailed explanation-1: -Iron and magnesium are the elements that are required for the synthesis of chlorophyll in plants.

Detailed explanation-2: -Manganese is involved in the formation of chlorophyll and helps plants use nitrogen. It is more available to plants in acidic soils than in alkaline soils. Without enough manganese, plants may have yellowish older leaves with green veins.

Detailed explanation-3: -Magnesium is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth.

Detailed explanation-4: -Magnesium is one of thirteen mineral nutrients that come from soil, and when dissolved in water, is absorbed through the plant’s roots. Sometimes there are not enough mineral nutrients in soil and it is necessary to fertilize in order to replenish these elements and provide additional magnesium for plants.

Detailed explanation-5: -Magnesium acts as a phosphorus carrier in plants and is essential for phosphate metabolism. Furthermore, it is also needed for cell division and protein formation, activation of several enzyme systems and is an essential component for plant respiration.
