Answer

To solve the matching question, we will analyze each receptor type in Column 1 and find the corresponding example from Column 2.

### Step-by-Step Solution:

1. **Identify the first receptor type: Stator receptor (A)**
- Stator receptors are responsible for maintaining equilibrium and balance. They are located in the inner ear, specifically in the structures known as cristae and maculae.
- **Match:** A → 2 (Cristae and maculae in the internal ear)

2. **Identify the second receptor type: Caloreceptor (B)**
- Caloreceptors are sensitive to heat and are found in the skin. They help in sensing temperature changes.
- The example for caloreceptors is Ruffini's organs, which are located in the skin and respond to heat.
- **Match:** B → 3 (Ruffini's organs in skin)

3. **Identify the third receptor type: Phonodceptor (C)**
- Phonodceptors are sound receptors located in the ear. The organ of Corti is the structure responsible for hearing and contains these receptors.
- **Match:** C → 1 (Organ of Corti)

4. **Identify the fourth receptor type: Proprioreceptor (D)**
- Proprioreceptors are found in muscles, tendons, and joints. They help in sensing the position and movement of the body.
- The Golgi-Mazzoni organ is an example of a proprioreceptor that detects muscle tension.
- **Match:** D → 4 (Golgi-Mazzoni organ)

### Final Matches:
- A → 2 (Cristae and maculae in internal ear)
- B → 3 (Ruffini's organs in skin)
- C → 1 (Organ of Corti)
- D → 4 (Golgi-Mazzoni organ)

### Summary of Matches:
- **A. Stator receptor** → **2. Cristae and maculae in internal ear**
- **B. Caloreceptor** → **3. Ruffini's organs in skin**
- **C. Phonodceptor** → **1. Organ of Corti**
- **D. Proprioreceptor** → **4. Golgi-Mazzoni organ**
