Correct Answer: B

Solution:

  • This sequence represents the order in which a cell progresses through the different stages of the cell cycle:
  1. G1 phase (Gap 1): The cell grows and carries out normal functions.
  2. S phase (Synthesis): DNA is replicated.
  3. G2 phase (Gap 2): The cell continues to grow and prepares for mitosis.
  4. M phase (Mitosis): The cell divides its copied DNA and cytoplasm to form two new cells.
