A. Perpendicular to both the direction of polarization and the direction of propagation
B. Perpendicular to the direction of polarization and parallel to the direction of propagation
C. Parallel to the direction of polarization and perpendicualar to the direction of propagation
D. Parallel to both the direction of polarization and the direction of propagation

Answer

To solve the question regarding the plane of polarization for linearly polarized light, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Linearly Polarized Light**:
- Linearly polarized light means that the electric field vector oscillates in a single plane. This plane is defined by the direction of the electric field and the direction of wave propagation.

2. **Identify the Components**:
- In a typical three-dimensional coordinate system, we can represent the electric field (E), magnetic field (B), and direction of propagation (k) of the wave. For linearly polarized light, the electric field oscillates in a specific direction, while the magnetic field oscillates perpendicular to it.

3. **Define the Plane of Polarization**:
- The plane of polarization is the plane that contains the direction of the electric field vector (E) and is perpendicular to the direction of wave propagation (k).

4. **Analyze the Options**:
- The options provided likely include various relationships between the direction of polarization and the direction of propagation.
- We need to determine which option correctly describes the relationship for linearly polarized light.

5. **Select the Correct Option**:
- Since the electric field is restricted to a single plane, the direction of polarization is parallel to the electric field and perpendicular to the direction of propagation. Thus, the correct option would be the one that states that the plane of polarization is parallel to both the direction of polarization and the direction of propagation.

### Conclusion:
- The correct answer is that for linearly polarized light, the plane of polarization is parallel to both the direction of polarization and the direction of propagation.
