Correct Answer :

Option A

A-II, B-III, C-IV, D-I

A-II, B-III, C-IV, D-I

Solution :

To match each phase in List I with the correct activity in List II, we consider the known characteristics of the cell cycle phases.

Phase G1 (A) – During G1 the cell is metabolically active, grows, but does not replicate its DNA. This description matches activity II (“Cell is metabolically active and continuously grows but does not replicate DNA”). Hence, A ↔ II.

Phase S (B) – In the S phase DNA synthesis occurs, so the amount of DNA per cell doubles. This corresponds to activity III (“Synthesis of DNA occurs and the amount of DNA per cell doubles”). Therefore, B �� III.

Phase G2 (C) – After DNA synthesis, the cell prepares for division by synthesizing proteins required for mitosis while growth continues. This matches activity IV (“Proteins are synthesized while cell growth continues”). Thus, C ↔ IV.

Phase M (D) – The M phase is where actual cell division (mitosis) takes place. This aligns with activity I (“Actual cell division occurs”). Hence, D ↔ I.

Putting the matches together gives the complete answer:

A‑II, B‑III, C‑IV, D‑I.
