The Earth's solid inner core results from the fact that
A)   the outer core is heated and melted by friction between the core and the mantle, and this heating does not extend to the inner core.
B)   the melting temperature of an iron-nickel mixture increases with increasing pressure and rises above the actual temperature in the inner core.
C)   the inner core has a different composition than the outer core, with a higher melting temperature.
D)   the temperature of the inner core is lower than the temperature of the outer core, producing a “temperature inversion.”
