Solution

The correct option is A polyploidy
Polyploidy is the phenomenon of having more than two genomes or two sets of chromosomes. It occurs in nature due to the failure of chromosomes to separate at the time of anaphase either due to non-disjunction or due to non-formation of spindle. Cytokinesis does not occur after telophase stage leading to polyploidy.
So, the correct answer is 'polyploidy'

Q. A cell at 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 telophase stage. There is no formation of cell plate and thus the cell is containing more number of chromosomes as compared to other dividing cells. This would result in:
