Explanation:

Different materials have different properties. The absorption and reflection of sound waves by a material depend on its physical characteristics. Each material will absorb and reflect sound waves at different ratios. For example, soft materials like foam tend to absorb more sound (higher absorption ratio) while hard materials like concrete tend to reflect more sound (higher reflection ratio). It's not about high or low frequencies in a simple "similar" or "different" way across all materials in the first, third options. And the fourth option is incorrect as different materials don't have the same absorption - reflection ratios.

Answer:

at different ratios of absorption and reflection
