Explanation:

The inner core is the innermost part of earth and due to high temperatures (more than 60000 Celsius) it ought to be in a liquid state. But researches have shown that it is in a solid state due to extreme pressure of the overlying layers.
Inner core also happens to be the densest layer. Infact the density of earth decreases as one moves away from the centre towards the surface.
