Explanation

The correct option is Image 3, as it accurately portrays the lateral inversion of the original figure across the vertical mirror line.
In a vertical mirror image, left and right are interchanged while top and bottom remain the same.
The number '5' on the left moves to the right and is horizontally flipped.
The circle on the right moves to the left, and its shaded quadrants (top-left and bottom-right) are mirrored to become top-right and bottom-left.
The shading on the bottom-right of the central shape is correctly reflected to the bottom-left.

Option A: Image 2 is incorrect because it fails to show any reflection. The elements remain in their original positions and orientations, making it identical to the question figure, not its mirror image.
Option C: Image 4 is incorrect because it shows an incomplete or partial reflection. While the '5' and the central shape are correctly mirrored, the shading within the circle is not reflected; it remains the same as the original figure.
Option D: Image 5 is incorrect because it depicts a water image, which is a vertical reflection (upside-down), not a lateral (horizontal) reflection as required for a mirror image.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests understanding of spatial and logical reasoning, specifically the concept of mirror images (lateral inversion) as background academic context rather than a clinical decision trigger.
This question is from the General Intelligence and Reasoning section of the nursing exam and does not have direct clinical relevance.
Strong problem-solving and analytical skills, which are tested by such questions, are crucial for nurses in making quick, logical decisions during patient care, interpreting data, and troubleshooting equipment.
What if the mirror was placed horizontally at the bottom? The result would be a 'water image' (similar to Image 5), where the figure is flipped vertically (top becomes bottom, and bottom becomes top).

How to Approach the Question

First, identify the type of question. This is a non-verbal reasoning question asking for a mirror image.
Note the position of the mirror, indicated by 'AB line'. A vertical line means a left-right (lateral) inversion.
Break down the original figure into its basic components: the number '5', the circle with shaded parts, and the central shape with shading.
Apply the rule of lateral inversion to each component individually. Imagine how each part would look when flipped horizontally.
Mentally construct the complete mirror image by combining the reflected components.
Compare your constructed image with the given options and eliminate the ones that have errors, such as no reflection, partial reflection, or a different type of reflection (like a water image).
