Answer- Diffuse reflection.
Here angle of incident is same but angle of reflection is different for single incident angle, hence it is diffuse reflection. Note that in case of regular reflection angle of reflection is equal to angle of incident. Reflection from regular surfaces (glass) is regular reflection and reflection from irregular surfaces (tree, rough surfaces, wall) is diffuse reflection.
Above case is neither a diffraction (since light is not bending towards corner of obstacle) and nor a refraction (since light is not changing its medium).
I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks...
