Mechanical waves are disturbances that require a medium to propagate, and they can travel through various types of media. Here’s a breakdown of the options provided:

1. A liquid: Mechanical waves can travel through liquids, such as sound waves in water.
2. A gas: Mechanical waves can also travel through gases, for example, sound waves traveling through air.
3. A solid: Additionally, mechanical waves can move through solids, such as seismic waves that travel through the Earth.

Given that mechanical waves can indeed propagate through all three types of media—liquids, gases, and solids—the correct answer to the question is:

Final Answer

All of these.
