Directions: Choose the letter of the best answer.

The sun is the closest star to Earth, and it plays a crucial role in supporting life on our planet. The sun is primarily composed of hydrogen and helium, which undergo nuclear fusion to produce light and heat. This energy sustains life on Earth by providing warmth, enabling photosynthesis, and driving weather patterns. Solar energy is also harnessed by humans using solar panels, which convert sunlight into electricity. The sun's light takes approximately 8 minutes and 20 seconds to travel from the sun to Earth, a distance of about 93 million miles.
