Dear student,

The deficiency of potassium in plants is first visible in the leaves. They start turning yellow and brown scorches are also seen. Similarly, the first symptoms of nitrogen deficiency in plants are also observed in the yellowing of leaves. This is because plants are unable to make enough chlorophyll and hence start appearing pale green or yellow.

So, the correct answer is 'Senescent leaves'.
