$A$ cell at the telophase stage is observed by a student in a plant brought from the field. He tells his teacher that this cell is not like other cells at the telophase stage. There is no formation of a cell plate,and thus the cell contains a higher number of chromosomes compared to other dividing cells. This would result in:

• A
  somaclonal variation
• B
  polyteny
• C
  aneuploidy
• D
  polyploidy
