Option 1 states that both statements are true, and Statement II is the correct explanation of Statement I. However, this is not accurate.
Statement I is true, as sound waves can indeed travel through a medium such as air or water. However, it is false to say that sound waves can travel through a vacuum. Since a vacuum is an absence of matter, there is no medium for sound waves to propagate through.
Statement II is true, as light is an electromagnetic wave and can travel through a vacuum. Unlike sound waves, light does not require a medium to travel and can move through empty space.
Therefore, Option 4 is the correct answer, stating that Statement I is false (sound waves cannot travel through vacuum) but Statement II is true (light can travel through vacuum).
