"temperature and type of medium" is correct.

Explanation (brief):
- The speed of sound depends on the medium's mechanical properties (type): its stiffness/elasticity (bulk modulus, Young's modulus) and its density. Different materials (air, water, steel) therefore give very different speeds.
- In gases the speed also depends on temperature: v = sqrt(γRT/M) (so v ∝ sqrt(T) for an ideal gas). For solids and liquids v ≈ sqrt(elastic modulus / density).
- The absolute volume of the medium (e.g., size of the container) does not directly set the speed of sound (only alters it if it changes density, temperature, or elastic properties).
