Answer:
The answer is: Because solids are the most sense.
Option (b) is the correct answer.
Step-by-step explanation:
The distance between molecules in solids r very small.Because they are so close, they can collide very quickly, i.e. it takes less time for a molecule of the solid to 'bump' into its neighbor. Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids.It is true that sound travels faster in solids. This is because in solid substances, molecules are much closer to each other due to which transfer of energy is much faster.
On the other hand, molecules in a liquid and gas are farther apart from each other due to which there will be less transfer of energy. As a result, sound does not travel quickly through liquids and gases.
Thus, we can conclude that sound travels most quickly through solids because the molecules in solids are very close together.
