The process to study cell division in laboratories is by preparing the microscopic slide with growing root tips and the most commonly used is Onion. The root tips are taken and flattened on a microscopic slide. To be able to observe the chromosome clearly the onion root tip cells are treated with DNA specific stains such as Acetocarmine or Feulgen. This helps the different stages of the supercoiled chromosomes to be visible under the microscope.
So, the correct answer is option D.
