i wanna say 11 forgive me if wrong.
Explanation:
I'm going to say a Human.
In one simple statement, Humans have survived all of earth's devastation because of evolution. At one point it is believed that the earth had changing conditions including that some of the food that we hunted in waters became extinct. Then, as lack of food grew, We gained the ability to walk on land. As this happened, we began to adapt to our surroundings, including gaining the ability to walk on two legs and use tools

Yes, thank you for coming back and supplying the list of choices.
At the level of Physics all the way up to somewhere in college, <em>choice-a)</em>
is not a property of light.

Answer:
The types of reflection are; specular and diffuse. This depends on the fine or smooth nature of the surface where reflection occurs.
A mirror has a smoother surface than that of a yellow vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes the solid yellow vase.
Explanation:
Reflection is one of the properties of light waves which can be observed when light strikes a smooth plane surface. It is the throwing of light back through its initial path. In reflection, the angle of incidence is equal to the angle of reflection.
There are two types of reflection; specular and diffuse. Specular reflection occurs when light rays are reflected from a fine smooth surface, while diffuse reflection is observed when light rays are reflected in all directions due to the rough nature of the surface. Comparing the surfaces of a mirror and vase, that of a mirror is smoother than that of a vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes a solid yellow vase.
