Explanation:
outer core
upper mantle
lower mantle
The inner core is the hottest layer among the options listed, and the coolest layer is the upper mantle.
1. **Inner Core:** The inner core is the innermost layer of the Earth, and it is primarily composed of solid iron and nickel. Despite being solid, it is the hottest layer in the Earth, with temperatures reaching up to around 5,000 to 6,000 degrees Celsius (9,000 to 10,800 degrees Fahrenheit). The intense heat in the inner core is due to the immense pressure from the layers above, which prevents the solid iron from melting.
2. **Outer Core:** The outer core surrounds the inner core and is primarily composed of liquid iron and nickel. While still extremely hot, it is cooler than the inner core, with temperatures ranging from about 4,000 to 5,000 degrees Celsius (7,200 to 9,000 degrees Fahrenheit).
3. **Upper Mantle:** The upper mantle is a layer of solid rock above the outer core and extends to a depth of about 670 kilometers (416 miles). It is cooler than both the inner and outer core, with temperatures decreasing with depth, but it is still quite hot, ranging from about 500 to 900 degrees Celsius (932 to 1,652 degrees Fahrenheit) near the boundary with the crust.
4. **Lower Mantle:** The lower mantle lies beneath the upper mantle and extends from about 670 kilometers (416 miles) to about 2,891 kilometers (1,796 miles) deep. It is also solid and hot, with temperatures increasing with depth, ranging from about 900 to 3,700 degrees Celsius (1,652 to 6,692 degrees Fahrenheit) at the boundary with the core.

Answer:
C
Explanation:
The correct answer is - Focus.
Focus of the earthquake, also referred to as hypocenter, is the location/point where the earthquake starts. It is usually few kilometres below the surface. At this spot the ground raptures after which seismic waves start radiating outward in all directions. The focus is located below the epicenter, or rather the epicenter is above it because the location of the epicenter is determined by the location of the focus, so the epicenter represents the closest point on the surface of the Earth from where the focus is.
