The correct answer is A. 5500°C.
The sun is a giant ball of hot gas. The temperature at the surface of the sun is about 5500°C. This is much hotter than anything on Earth. The sun’s heat comes from nuclear reactions that take place in its core. These reactions convert hydrogen into helium, releasing a tremendous amount of energy.
The sun’s heat is essential for life on Earth. It provides the energy that plants need to grow, and it helps to regulate the Earth’s climate. Without the sun, Earth would be a cold, lifeless planet.
The sun is a very important part of our solar system. It is the largest object in the solar system, and it provides the light and heat that make life on Earth possible. The sun is also a very active object. It has a magnetic field that is constantly changing, and it produces solar flares and coronal mass ejections. These events can have a significant impact on Earth’s atmosphere and technology.
The sun is a fascinating object, and it is still not fully understood. Scientists are constantly learning new things about the sun, and they are working to understand its role in the solar system and its impact on Earth.
The other options are incorrect because they are too low. The temperature of the sun is much hotter than anything on Earth.
