Necrosis refers to 

  1. Inhibition of cell division
  2. Delay in flowering
  3. Death of tissues
  4. Falling of leaves
Correct Answer: Option(c)
Solution: When a living organism's cells or tissues die or degenerate, the condition is called necrosis. In a plant, necrosis causes leaves, stems and other parts to darken and wilt. Necrosis weakens the plant and makes it more susceptible to other diseases and pests. 
Thus, the correct answer is 'Death of tissues.'
