### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the specific type of sensation that the Organs of Ruffini are receptors for.

2. **Reviewing the Options**: The options provided are:
- A) Cold
- B) Pressure
- C) Heat
- D) Touch

3. **Analyzing Each Option**:
- **Option A: Cold** - The sensation of cold is primarily detected by Krause's end bulbs, not the Organs of Ruffini. Therefore, this option is incorrect.
- **Option B: Pressure** - The sensation of pressure is primarily detected by Pacinian corpuscles, which are different from the Organs of Ruffini. Thus, this option is also incorrect.
- **Option C: Heat** - The Organs of Ruffini are indeed responsible for detecting heat sensations. They are located in the deeper layers of the dermis and respond to changes in temperature.
- **Option D: Touch** - The sensation of touch is primarily detected by Meissner's corpuscles, which are located in the outer surface of the dermis. Hence, this option is incorrect.

4. **Conclusion**: Based on the analysis, the Organs of Ruffini are receptors for **heat**.

### Final Answer:
The Organs of Ruffini are receptors of **heat**.
