How are things visible to us? 

You need to explain what the object looks like. Now we know that light is the source that makes things visible to us. Without light, you can't see anything around you. When light hits an object, it reflects or bounces back into our eyes and becomes visible. Without reflection, it wouldn't be visible to us. This is because when the light from the light source hits an object, it reflects off and returns to the eye, forming an image of the same size as the object, although the lens of the eye is virtually upright. 

Therefore, the correct option is B.
