its d

Right.

To determine the correct description of the Earth's inner core, we can use scientific knowledge and research. The Earth's inner core is known to be solid and extremely hot, with temperatures estimated to be as high as 6,000 degrees Celsius (10,800 degrees Fahrenheit). To arrive at this conclusion, scientists have relied on various indirect methods such as studying seismic waves and analyzing how they travel through the Earth's interior.

Therefore, the correct answer to the question is D) solid and extremely hot, rather than C) liquid and cool.
