keywords: 

{'velocity': [0, 2, 2, 6], 'sound': [4, 3, 10, 15], 'solids': [0, 0, 0, 4], 'liquids': [0, 0, 0, 1], 'gases': [0, 0, 5, 12], 'minimum': [0, 0, 0, 4], 'media': [2, 0, 0, 2]}

The correct answer is option 4: "The velocity of sound is maximum in solids and minimum in gases."

Let`s analyze the other options to understand why they are not correct.

Option 1 states that the velocity of sound does not depend upon the nature of media. This is incorrect because the velocity of sound does vary depending on the medium through which it travels. For example, sound travels faster in solids than in gases or liquids.

Option 2 suggests that the velocity of sound is maximum in gases and minimum in liquids. This is also incorrect because sound actually travels faster in liquids compared to gases. Liquids are denser than gases and therefore can transmit sound waves more effectively.

Option 3 claims that the velocity of sound is maximum in solids and minimum in liquids. This is partially correct because sound does travel faster in solids than in liquids. However, it fails to acknowledge that sound also travels faster in solids than in gases.

Therefore, option 4 is the correct answer as it accurately states that the velocity of sound is maximum in solids and minimum in gases.
