C. (i) Interphase(ii) M- phase (iii) G2 phase (iv) G1 phase
D. (i) karyokinesis (ii) cytokinesis (iii) G1 phase (iv) S phase

Answer

To solve the question, we need to fill in the blanks based on our understanding of the cell cycle. Let's break it down step by step.

### Step 1: Identify the two basic phases of the cell cycle.
The cell cycle is divided into two main phases:
1. Interphase
2. M-phase (Mitotic phase)

**Hint:** Remember that the cell cycle consists of phases where the cell prepares for division and the phase where it actually divides.

### Step 2: Determine the phase during which the cell is metabolically active and continuously grows.
During the G1 phase of Interphase, the cell is metabolically active and grows in size. This is the phase where the cell performs its normal functions and prepares for DNA replication.

**Hint:** Think about which phase of the cell cycle is primarily focused on growth and preparation before DNA synthesis.

### Step 3: Identify when centrioles duplicate in the cytoplasm.
Centriole duplication occurs during the S phase of Interphase. In this phase, DNA is replicated, and the centrioles also duplicate to prepare for cell division.

**Hint:** Recall that the S phase is specifically known for DNA synthesis, and it is also the time when centrioles are duplicated.

### Final Answers:
Now we can fill in the blanks:
(A) The cell cycle is divided into two basic phases: **(i) Interphase** and **(ii) M-phase**.
(B) During **(iii) G1 phase**, the cell is metabolically active and continuously grows.
(C) Centrioles duplicate in the cytoplasm during **(iv) S phase**.

### Summary of Answers:
1. (i) Interphase
2. (ii) M-phase
3. (iii) G1 phase
4. (iv) S phase
