(A) The object $AB$ is placed such that point $A$ is at the centre of curvature $(C = 2f)$ of the concave mirror. Since $A$ is at the centre of curvature, its image $A'$ will also be formed at the centre of curvature $A' = A$. Point $B$ is placed at a distance greater than $2f$ from the mirror. For an object placed beyond $C$, the image is formed between $C$ and $f$, is real, inverted, and diminished. Since $B$ is at an angle of $45^{\circ}$ with the principal axis, the image $B'$ will also be formed below the principal axis. As the object $AB$ is tilted away from the mirror, the image $B'$ will be formed such that it is inverted and points towards the principal axis. Comparing this with the given options, option $A$ correctly represents the inverted image $A'B'$ where $A'$ coincides with $A$ and $B'$ is formed between $C$ and $f$ pointing downwards.

The shape of the image formed of an object $AB$ due to the concave mirror shown in the figure is best represented by (assume point $A$ is at the centre of curvature of the mirror):-

Assertion : $A$ point object is placed at a distance of $26 \ cm$ from a convex mirror of focal length $26 \ cm$. The image will not form at infinity.
Reason : For the above-given system,the equation $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$ gives $v = \infty$.
