(c) : The figure given in the question shows a stage of mitotic cell division called as telophase stage. The individual chromosomes are no longer seen and chromatin material tends to collect in a mass at the two poles. This is the stage which shows the following key events: - Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. - Nuclear envelope assembles around the chromosome clusters. - Nucleolus, Golgi complex and ER reform.
