Solution

The correct option is D
Mirror

Among the given options, light is necessary as it responsible for the sensation of vision or in other words it enables us to see. Without eyes, we can not sense light. The object is obviously necessary as we can not see something which does not exist (unless you are daydreaming). A mirror is required only when we want to see the reflection of the object. Hence, D is the correct answer.
