Answer

To solve the matching question, we will analyze each item in Column I and find the corresponding item in Column II based on the definitions and concepts from wave optics.

### Step-by-Step Solution:

1. **Analyze Item A:**
- **Description:** "The phenomenon of redistribution of light energy on account of superimposition."
- **Explanation:** This describes the process of interference, where two or more light waves superimpose to form a resultant wave, leading to a redistribution of energy.
- **Match:** A → q (Interference of light)

2. **Analyze Item B:**
- **Description:** "Emit continuous light waves of the same wavelength having constant phase difference."
- **Explanation:** This describes coherent sources, which are sources of light that maintain a constant phase relationship and have the same frequency and wavelength.
- **Match:** B → p (Coherent sources)

3. **Analyze Item C:**
- **Description:** "The phenomenon of bending of light around corners."
- **Explanation:** This describes diffraction, which is the bending of light waves around obstacles or through openings.
- **Match:** C → s (Diffraction of light)

4. **Analyze Item D:**
- **Description:** "The phenomenon of restricting the vibration of ordinary light."
- **Explanation:** This describes polarization, which is the process of restricting the vibrations of light waves to a particular direction.
- **Match:** D → r (Polarization of light)

### Final Matches:
- A → q (Interference of light)
- B → p (Coherent sources)
- C → s (Diffraction of light)
- D → r (Polarization of light)
