C. opaque
D. translucent

Explanation

To solve the question, "The objects which partially allow light to pass through it are called:", we need to analyze the definitions of the terms provided in the options: transparent, opaque, translucent, and luminous.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Transparent**: Objects that allow all light to pass through them, making objects behind them clearly visible (e.g., clear glass).
- **Opaque**: Objects that do not allow any light to pass through them (e.g., wood, metal).
- **Translucent**: Objects that allow some light to pass through, but not enough to see clearly through them (e.g., frosted glass, wax paper).
- **Luminous**: Objects that emit their own light (e.g., the sun, light bulbs).

2. **Identify the Correct Term**:
- The question specifically asks for objects that "partially allow light to pass through."
- From the definitions, **translucent** is the term that fits this description, as it allows some light to pass but does not provide a clear image.

3. **Conclusion**:
- Therefore, the correct answer to the question is **translucent**.

### Final Answer:
The objects which partially allow light to pass through them are called **translucent**.
