which factors affect the speed of sound?\ntype and volume of medium\ntemperature and type of medium\nvolume…

Brief Explanations:

The speed of sound depends on the type of medium (e.g., solid, liquid, gas - sound travels fastest in solids as particles are closely packed for better vibration transfer). Temperature also affects it. In a given medium, higher temperature means more kinetic energy of particles, allowing sound waves (which are vibrations) to propagate faster. Volume of the medium does not affect the speed of sound.

Answer:

B. temperature and type of medium
