All the following statements are correct except (for real objects)

Options

A. (A) the magnification produced by a convex mirror is always less than one
B. (B) a virtual, erect and same sized image can be obtained using a plane mirror
C. (C) a virtual, erect, magnified image can be formed using a concave mirror
D. (D) a real, invered same sized image can be formed using a convex mirror

Explanation

To solve the question regarding which statement is incorrect about real objects in the context of reflection of light, we will analyze each option step by step.

### Step 1: Analyze Option A
**Statement:** The magnification produced by a convex mirror is always less than 1.

**Explanation:** This statement is correct. A convex mirror always produces a virtual image that is diminished (smaller than the object), hence the magnification (which is the ratio of the height of the image to the height of the object) is always less than 1.

### Step 2: Analyze Option B
**Statement:** A virtual erect and same-sized image can be obtained using a plane mirror.

**Explanation:** This statement is also correct. A plane mirror produces a virtual image that is the same size as the object and is erect.

### Step 3: Analyze Option C
**Statement:** A virtual erect magnified image can be formed using a concave mirror.

**Explanation:** This statement is correct as well. When the object is placed between the focus and the pole of a concave mirror, the image formed is virtual, erect, and magnified. This is often used in applications like dental mirrors.

### Step 4: Analyze Option D
**Statement:** A real inverse same-sized image can be formed using a convex mirror.

**Explanation:** This statement is incorrect. A convex mirror cannot produce a real image; it always produces a virtual image that is erect and diminished. Therefore, a real inverse image cannot be formed using a convex mirror.

### Conclusion
The incorrect statement among the options given is **Option D**.

### Summary of the Solution
- Option A: Correct (magnification < 1 for convex mirrors)
- Option B: Correct (plane mirror gives same-sized virtual image)
- Option C: Correct (concave mirror can give magnified virtual image)
- Option D: Incorrect (convex mirrors do not produce real images)
