    Solution:

     Concept- The deficiency symptoms depend upon element to element and that they don't seem to be seen when the deficient element or nutrient is facilitated to the plant. However if the deprivation continues it's going to eventually result in the death of the plant.
    Necrosis is especially the cell injury which results in the premature death of cells in living tissue. Factors like infection or trauma external to the cell or tissue can cause necrosis which ends up within the unregulated digestion of cell components.
    Potassium deficiency causes chlorosis which further leads to chlorosis; calcium causes stunt growth and further magnesium ends up in high necrosis in plants.
    -Ca, K ,Cu and Mg : The deficiency of these elements causes necrosis in plants. Necrosis is that the death of tissue and mainly of the leaf tissue.
    -N, K, S and Mo: The deficiency of these elements ends up in inhibition that's a disruption of the cellular division. Their absence symptoms appear within the older tissue.
    -N, S, Fe and Zn: the dearth of these elements causes chlorosis. it's defined because the loss of chlorophyll that ends up in yellowing of the leaves.
    -Mg, S, Mn and Ca: The deficiency of these elements results in the condition that flowers occur late and therefore the late flowering is liable for the late growth of fruit.
    Hence, the proper answer is option (1) .
