A cell at telophase stage is observed by...

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

A

polyploidy

B

somaclonal variation

C

polyteny

D

aneuploidy
