Assertion `:` The size of the mirrorr affect the nature of the image.
Reason `:` Small mirrorrs always forms a virtual image.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true and reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the given question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states: "The size of the mirror affects the nature of the image."
- This statement implies that the physical dimensions of the mirror (i.e., whether it is large or small) influence the type of image (real or virtual) that is formed.

### Step 2: Analyze the Assertion
- The nature of an image formed by a mirror primarily depends on the mirror's curvature (concave or convex), the focal length, and the distance of the object from the mirror.
- The size of the mirror does not inherently change whether the image is real or virtual. For example, a concave mirror can produce a real image if the object is beyond the focal point, regardless of its size.

### Conclusion for Assertion
- Therefore, the assertion is **false** because the size of the mirror does not affect the nature of the image.

### Step 3: Understand the Reason
The reason states: "Small mirrors always form a virtual image."
- This statement suggests that if a mirror is small, it will only produce virtual images.

### Step 4: Analyze the Reason
- A small concave mirror can form a real image if the object is placed at a suitable distance (beyond the focal length).
- A small convex mirror will always produce a virtual image, but this is not a characteristic of the size itself; rather, it is a property of the type of mirror.

### Conclusion for Reason
- Hence, the reason is also **false** because small mirrors do not always form virtual images; it depends on the type of mirror and the position of the object.

### Final Conclusion
Both the assertion and the reason are false. Therefore, the correct answer is that both statements are incorrect.
