\nStatement A is correct: The Mohorovicic discontinuity (Moho) is the boundary between the Earth’s crust and the mantle. Statement B is correct: The mantle constitutes about 84% of Earth’s volume and around 67% of its mass. Statement D is correct: Due to immense pressure, the inner core is in a solid state despite extremely high temperatures.
