Solution

The correct option is B Ca, Mg, Cu and K
The concentration of the essential element below which plant growth is retarded is termed as critical concentration. The element is said to be deficient when present below the critical concentration. Since each element has one or more specific structural or functional role in plants, so plants certain morphological changes in the limitation of any particular element. These externally visible morphological change which are produced due to absence or deficiency of essential mineral elements, are called deficiency symptoms. Necrosis is a common deficiency symptom. It refers to the death of tissue, particularly leaf tissue. It is caused by the deficiency of Ca, Mg, Cu and K.
