A : 3-D movies are produced by pojecting two images onto a screen, with polarizing dissections that are `90^(@)` relative to one another.
R : When your eyes view 3D wearing 3D glasses, your right eye sees one view and left eye sees the other view, these views combines in the brain and produce 3D effect.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true and R is not the correct explanation of A
C. A is true and R is false
D. Both A and R are false

Answer

To analyze the given assertion (A) and reason (R) regarding 3D movies, we can break down the explanation step by step.

### Step 1: Understanding the Assertion (A)
The assertion states that "3-D movies are produced by projecting two images onto a screen, with polarizing dissections that are 90 degrees relative to one another."

- **Explanation**: In 3D movies, two separate images are projected simultaneously. Each image is polarized in a different direction (90 degrees apart). This is essential because it allows each eye to receive a different image, creating a sense of depth.

### Step 2: Understanding the Reason (R)
The reason states that "When your eyes view 3D wearing 3D glasses, your right eye sees one view and left eye sees the other view; these views combine in the brain and produce a 3D effect."

- **Explanation**: The 3D glasses have polarizing filters that correspond to the polarization of the images projected. The right lens allows only the image intended for the right eye to pass through, and similarly for the left lens. When the brain receives these two slightly different images, it processes them together, resulting in the perception of depth and a 3D effect.

### Step 3: Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, we can conclude that the correct answer to the question is that both A and R are true, and R is the correct explanation of A.

### Final Answer:
Both assertion (A) and reason (R) are true, and R is the correct explanation of A.
