A full-length image of a distant tall building can definitely be seen by using a convex mirror.
Explanation:
The image developed by the convex mirror is always small, upright and virtual. It is also called as divergent mirrors as rays of light falling on mirror diverges from one point and forms a virtual image of an object.
It is utilised in side and rear view of the vehicles.

Answer:
A full-length image of a distant tall building can be seen by using a convex mirror.
Explanation:
When we use a mirror to see an object, the image formed can be either real or virtual. In the case of a real image, it can be projected on a screen, while a virtual image cannot be projected.
Types of Mirrors:
There are three types of mirrors - concave, convex, and plane mirrors.
1. Concave Mirror:
- A concave mirror is curved inward, like the inside of a spoon.
- It can form both real and virtual images, depending on the position of the object.
- When the object is placed beyond the focal point, a real and inverted image is formed.
- However, as the object is distant in this scenario, the image formed by a concave mirror will be small and inverted. It will not be a full-length image of the building.
2. Plane Mirror:
- A plane mirror is a flat mirror with a reflective surface.
- It forms only virtual images, which appear to be behind the mirror.
- The size and orientation of the image formed in a plane mirror are the same as that of the object.
- Therefore, a plane mirror cannot produce a full-length image of a distant tall building.
3. Convex Mirror:
- A convex mirror is curved outward, like the back of a spoon.
- It forms only virtual images, which are erect and diminished in size.
- Due to its shape, a convex mirror has a wide field of view, making it suitable for use in rear-view mirrors of vehicles.
- When using a convex mirror, the image of a distant tall building will be virtual, erect, and diminished in size. However, it will give a full-length view of the building.
Therefore, the correct answer is option 'B' - a convex mirror.
