Malika is writing an essay about the Sun. Below is the first paragraph in the essay.The Sun is an average-size star that is located at the center of the solar system. This hot, glowing ball of gas has a diameter of 1,393,000 km. This means 109 Earths would fit side by side across the diameter of the Sun. At the surface, the Sun’s temperature is about 550 degrees Celsius. Earth is located just under 150 million kilometers from the Sun.Malika quickly realizes this paragraph contains an error. Which statement corrects the error?

A
The Sun is a large star, not an average-size star.
B
The Sun is not a glowing ball of gas—it is solid.
C
The Sun’s surface temperature is about 5,500 degrees Celsius.
D
Earth is located over 300 million kilometers from the Sun.
