Final answer:

The brain constructs a perception of a world full of light through sensory transduction, converting light into electrical impulses via the peripheral nervous system to create our visual experience.

Step-by-step explanation:

How Does the Brain Create a World Full of Light?

The brain constructs our perception of a world full of light through a process known as sensory transduction. This process involves converting various forms of stimuli from our environment into electrical impulses. Our visual system, specifically, converts the light that enters our eyes into signals that our brain interprets, thus creating the experience of seeing. These impulses are relayed through the peripheral nervous system to the brain, where they are processed to form our perception of the world around us. Hence, the correct answer to how the brain, despite being in total darkness, builds for us a world full of light is (c) Via electrical impulses.

It's important to note that while the mind is non-physical and does not generate light, the brain is physical and responds to physical stimuli, including light. Plants are critical in this relationship with light; they use photosynthesis to convert sunlight into chemical energy, which sustains a vast array of life forms, including humans.
