Hint:The surface of rocks or water surfaces usually acts as a mirror. In the case of the surface of the water which generally has very less or almost no irregularity, act as a plane mirror and hence regular reflection takes place whereas on rock surfaces which generally have many irregularly irregular (diffused) reflection takes place. Using this information, we can find out the correct answer.

Complete answer:
When a ray of light is incident on an irregular surface like a sea rock, the light is scattered (reflected) that is the light rays are not parallel to each other and traveling in different directions away from the surface, thus the reflection produced is called a diffused (or irregular) reflection.

Hence option B is the correct answer.

Note:If the rays of light before reflection and after reflection that is incident ray and reflected ray remain parallel, then the reflection is called regular reflection. If the rays of light before reflection are parallel to each other but are not parallel after reflection, then the reflection is called irregular or diffused reflection and if a light ray falls on a refracting surface but its incidence angle is greater than the critical angle then the incident ray is reflected in the same medium and the phenomenon is called total internal reflections.
