The laws of reflection hold true for:

Options

A. plane mirrors only
B. concave mirrors only
C. convex mirrors only
D. all reflecting surfaces

Explanation

**Step-by-Step Solution:**

1. **Understanding the Laws of Reflection**: The laws of reflection state that when a ray of light strikes a reflecting surface, the angle of incidence is equal to the angle of reflection. This is true for all types of mirrors and reflecting surfaces.

2. **Analyzing the Options**:
- **Option 1: Plane mirrors only**: While the laws of reflection do apply to plane mirrors, they are not limited to just plane mirrors. Therefore, this option is incorrect.
- **Option 2: Concave mirrors only**: Similar to plane mirrors, concave mirrors also follow the laws of reflection, but again, they are not the only type of mirrors that do so. Hence, this option is also incorrect.
- **Option 3: Convex mirrors only**: Convex mirrors follow the laws of reflection as well, but like the previous options, they do not encompass all reflecting surfaces. Thus, this option is incorrect too.
- **Option 4: All reflecting surfaces**: This option states that the laws of reflection hold true for all types of reflecting surfaces, including plane, concave, and convex mirrors, as well as any other reflective materials. This is the correct option.

3. **Conclusion**: The laws of reflection hold true for all reflecting surfaces, making option 4 the correct answer.

**Final Answer**: The laws of reflection hold true for all reflecting surfaces.
