E-C-A-D-B

Solution :

To determine the correct sequence of stages in cell division, we need to look at the phases of the cell cycle. The cell cycle is broadly divided into two main periods: Interphase and the M phase (Mitotic phase).

1. Interphase is the preparatory phase where the cell grows and replicates its DNA. It consists of three sequential sub-phases:
- Gap 1 phase (G1 phase): The cell grows and performs normal metabolic roles. (Stage E)
- Synthesis phase (S phase): DNA replication occurs. (Stage C)
- Gap 2 phase (G2 phase): The cell grows further and prepares for division. (Stage A)

2. M phase is the actual division phase, which consists of two sequential processes:
- Karyokinesis: Nuclear division, where the replicated chromosomes are partitioned. (Stage D)
- Cytokinesis: Cytoplasmic division, which splits the cell into two daughter cells. (Stage B)

Combining these stages in chronological order gives:
Gap 1 phase (E) → Synthesis phase (C) → Gap 2 phase (A) → Karyokinesis (D) → Cytokinesis (B)

Therefore, the correct sequence of stages is E-C-A-D-B.
