Answer:

The correct answer is option C. That none of the DNA is damaged in the cells.

Explanation:

Control mechanisms in cells during cell division which ensure the proper division of the cells are called cell cycle checkpoints. There are three checkpoints in the cell cycle in meiosis or mitosis-

G1 checkpoint assesses the integrity of DNA.  There is intermediate S checkpoint between G1 checkpoint and G2 checkpoint checks if DNA replication is completed or not.

G2 checkpoint checks or assesses the proper chromosome duplication and that none of the DNA is damaged in the cell.

M checkpoint assesses the attachment of every kinetochore to a spindle fiber.
