The Correct Option is B
Solution and Explanation
To solve this matching problem, we need to align the stages of the cell cycle in List I with their respective descriptions in List II. Let's go through each pair:
- M Phase: This phase is known for mitosis or equational division, where the cell divides its chromosomes equally into two daughter cells. Therefore, M Phase matches with description IV: Equational division.
- G2 Phase: This is the phase following DNA replication and before mitosis. During this phase, the cell synthesizes proteins and other materials required for division. Therefore, G2 Phase matches with description I: Proteins are synthesized.
- Quiescent stage: Also known as the G0 phase, it is an inactive phase during which the cell has left the cycle and stopped dividing. Therefore, the Quiescent stage matches with description II: Inactive phase.
- G1 Phase: This phase occurs immediately after mitosis and is the interval before the initiation of DNA replication. Hence, the G1 Phase matches with description III: Interval between mitosis and initiation of DNA replication.
Thus, the correct matching is:
- A-IV
- B-I
- C-II
- D-III
Therefore, the correct answer is: A-IV, B-I, C-II, D-III.

Cell Cycle and Cell Division
Cell Cycle:
The sequence of events by which a cell copies itself synthesizes other constituents of the cell and eventually splits into two daughter cells is termed the cell cycle. The cell synthesizes all its constituents in a sequential pattern to make sure the proper division and distribution of components that occurs between the two daughter cells. Therefore, we can say that the cell cycle is the period of time between the development of new daughter cells and their further division.
Stages of Cell Cycle:
The cell cycle can be sub-divided into an additional category of Interphase. Meanwhile, the Interphase can be branched into 3 further stages, such as:
- G1 Phase - “Gap 1 Phase”
- S Phase - "Synthesis Phase"
- G2 Phase - "Gap 2 Phase"

Cell Division:
The division of the parent cells into two or more cells is called daughter cell, cell division takes place. In general, it occurs as a part of a larger cell cycle. All the cell reproduces by dividing into two, wherein each parental cell produces two daughter cells.
Stages of Cell Division:
Cell division can be widely divided into several sub-segments that result from Mitosis and Meiosis.
- Mitosis or (M Phase)
- Meiosis
