Detailed Solution

Concept- We must address the amplification that the automobiles' installed rearview mirrors cause in this inquiry. In cars, convex mirrors are utilized as rearview mirrors. Convex mirrors are bent outward, giving them an extremely broad field of vision. As a result, the motorist can see a lot more with the convex mirrors than with a regular mirror.
Formula used:

m = h i h o

Where,

m

is the magnification,

h i

is the height of the image and

h o

is the height of the image.
From the formula

m = h i h o

,
The criterion for a plane mirror is met if the magnification is equal to one, which indicates that the height of the image is equal to the height of the object. If the magnification is larger than one, it indicates that a concave mirror is necessary since the image's height is greater than the object's height. That indicates that the observer is only seeing a portion of the thing.
This implies that the height of the image should be less than the height of the object, which is the need for a convex mirror and gives the driver a full view, and that the magnification created by the rearview mirror of the cars should be less than one of the following vehicles.
Hence, the correct option is 1.
