Sound waves are mechanical waves, which means they require a medium (like solid, liquid, or gas) to travel. They cannot travel through a vacuum.

– Sound propagates through a medium by causing vibrations in the particles of that medium.
– In a vacuum, there are virtually no particles, so there is no medium for the sound waves to propagate through.

– Options A, B, and C state that sound waves can travel through water (liquid), air (gas), and steel (solid), respectively. These statements are correct as these are all forms of matter that can act as mediums for sound transmission.
– This is why sound cannot be heard in outer space, which is essentially a vacuum.
