Answer

To solve the question regarding the phases of the menstrual cycle and their corresponding periods, we will analyze each phase and its duration step by step.

### Step-by-Step Solution:

1. **Identify the Phases of the Menstrual Cycle:**
The menstrual cycle consists of four main phases:
- Menstrual Phase
- Proliferative Phase
- Ovulatory Phase
- Luteal Phase

2. **Examine Each Phase with Its Duration:**
- **Menstrual Phase:** This phase occurs from the **1st to the 4th day** of the cycle. During this time, the endometrium sheds, leading to menstruation.
- **Proliferative Phase:** This phase occurs from the **5th to the 13th day**. It is characterized by the regeneration of the endometrium after menstruation.
- **Ovulatory Phase:** This phase occurs on the **14th day** of the cycle. Ovulation, the release of an egg from the ovary, takes place during this phase.
- **Luteal Phase:** This phase lasts from the **15th to the 28th day**. It is marked by the formation of the corpus luteum, which secretes progesterone.

3. **Match Each Phase with Its Period:**
- (i) Menstrual phase: **1st - 4th day** (Correct)
- (ii) Proliferative phase: **5th - 13th day** (Correct)
- (iii) Ovulatory phase: **14th day** (Correct)
- (iv) Luteal phase: **15th - 28th day** (Correct)

4. **Conclusion:**
All four phases are correctly matched with their respective periods. Therefore, the correct answer is **1, 2, 3, and 4**.

### Final Answer:
The correct option is **1, 2, 3, and 4**.
