C) Raleigh waves
D) Love waves

P waves, or primary waves, can travel through both liquid and solid layers of the Earth, but the ability of S waves to travel through the Earth's inner core would indicate it is solid. However, it is the behavior of P waves, such as their speed and refraction, when they travel through the inner core that provides evidence of its solid state. S waves cannot travel through liquid, and their absence in the outer core supports its liquid state, but the question specifically asks about evidence indicating the inner core is solid, which is inferred from observations of P waves.
