D. It allows the flow of an electric current in the circuit.
<h3>
Why is it important to have a closed circuit?</h3>
Closed circuit allows the flow of current in the circuit from the battery to the bulb. If the circuit is open then the current will not reach to the bulb or other appliances.
So we can conclude that It is important to have a closed circuit because it allows the flow of an electric current in the circuit.

Answer:
》How can a camera help someone see something he or she wouldn't normally be able to see?
- Although the human eye is able to observe fast events as they happen, it is not able to focus on a single point of time. We cannot freeze motion with our eyes. With a camera, however, so long as there is enough light, we can freeze motion. ... The camera can capture 'the moment', while your eye cannot.
》In what way is laser different from light produced by other sources?
-The major difference between laser light and light generated by white light sources (such as a light bulb) is that laser light is monochromatic, directional and coherent. ... Light from a conventional sources, such as a light bulb diverges, spreading in all directions.
