o. rotation
o. translation

 Translation

Step-by-step explanation:

Definitions:

Reflection:- A reflection is a rigid transformation that create a mirror image of a the original figure across a line of reflection .

Rotation:-A rotation is a rigid transformation which rotates a the original figure by some degrees.

Translation:- A translation is a rigid transformation that maps every point of the original figure a fixed distance in a specific direction.

In the given figure , a trapezium is transformed to another trapezium such that there is no change in the size and orientation.

Also, the image and pre-image are not appearing as mirror images .

Each point of the image is moved fixed and equal distance in a particular direction .

⇒ The transformation is translation.
