C. दोनों
D. कोई नहीं

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about "अपारदर्शी वस्तु" which translates to "opaque objects" in English. Opaque objects are those that do not allow light to pass through them.

2. **Definition of Opaque Objects:**
Opaque objects are materials that do not allow any light to pass through. This means that when light hits these objects, it cannot be seen through them.

3. **Examples of Opaque Objects:**
Common examples of opaque objects include:
- Wood
- Metal
- Stone
- Thick paper
- Mirrors (which reflect light instead of allowing it to pass through)

4. **Contrast with Transparent and Translucent Objects:**
To further clarify, it is helpful to understand the difference between opaque, transparent, and translucent objects:
- **Transparent Objects:** These allow light to pass through completely (e.g., clear glass).
- **Translucent Objects:** These allow some light to pass through but not enough to see clearly through them (e.g., frosted glass).
- **Opaque Objects:** These do not allow light to pass through at all.

5. **Conclusion:**
Therefore, "अपारदर्शी वस्तु" refers to objects that do not allow light to pass through them, making them invisible from the other side.
