B. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.

Explanation:

Recent calculations indicate that the Earth's inner core is much hotter than previous experiments suggested (with a temperature of about 5000 degrees Celsius), since it can be at a temperature of 6000 degrees Celsius, almost as hot as the Sun's surface.
