Options

A. a-iii, b-v, c-i, d-ii
B. a-v, b-iv, c-i, d-iii
C. a-v, b-i, c-iv, d-ii
D. a-v, b-ii, c-iii, d-iv

Answer

To solve the matching question, we need to correctly pair each phase of the cell cycle with its corresponding description. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Phases**:
- G1 phase
- S phase
- G2 phase
- G0 phase

2. **Identify the Descriptions**:
- Replication of DNA
- Quiescent stage
- Condensation of chromatin
- Protein synthesis
- Interval between mitosis and initiation of DNA replication

3. **Match Each Phase with Its Description**:
- **G1 phase (a)**: This phase is primarily about cell growth, RNA synthesis, and protein synthesis. The correct match is **v. Interval between mitosis and initiation of DNA replication**.
- **S phase (b)**: This phase is specifically for DNA replication. The correct match is **i. Replication of DNA**.
- **G2 phase (c)**: This phase involves preparation for mitosis, including protein synthesis. The correct match is **iv. Protein synthesis**.
- **G0 phase (d)**: This phase is a resting state where the cell is not actively dividing. The correct match is **ii. Quiescent stage**.

4. **Final Matches**:
- G1 phase (a) → v. Interval between mitosis and initiation of DNA replication
- S phase (b) → i. Replication of DNA
- G2 phase (c) → iv. Protein synthesis
- G0 phase (d) → ii. Quiescent stage

5. **Choose the Correct Option**:
Based on the matches:
- A → v (5th)
- B → i (1st)
- C → iv (4th)
- D → ii (2nd)

Therefore, the correct option is: **A 5th, B 1st, C 4th, D 2nd**.
