C. Stanley Miller
D. Harold Urey

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the naming of water-bonded colloid droplets known as proteinoid microspheres.

2. **Identifying Key Terms**: The key terms in the question are "water-bonded colloid droplets" and "proteinoid microspheres."

3. **Reviewing Historical Context**: The concept of proteinoid microspheres is related to the origin of life and the theories proposed by scientists in this field.

4. **Evaluating Options**:
- **Option 1: Operin** - Incorrect. Operin is known for the naturalistic theory of the origin of life but did not name proteinoid microspheres.
- **Option 2: Sidney Fox** - Correct. Sidney Fox is credited with naming the water-bonded colloid droplets as proteinoid microspheres.
- **Option 3: Stanley Miller** - Incorrect. Miller is known for his experiments on the synthesis of organic molecules but did not name proteinoid microspheres.
- **Option 4: Harold Urey** - Incorrect. Urey collaborated with Miller on experiments related to the origin of life but did not name proteinoid microspheres.

5. **Conclusion**: The correct answer is that water-bonded colloid droplets have been named proteinoid microspheres by Sidney Fox.
