The correct answer to the question is : A) Sound waves.
EXPLANATION:
Before going to answer this question, first we have to understand sound wave.
A sound wave is a longitudinal wave which needs a medium for its propagation. It moves in the form of compression and rarefaction in a medium. The medium may be solid,liquid or gases.
Unlike sound waves, gamma waves, micro waves and UV waves do not require any medium for its propagation. They can travel in space also. They all are included in electromagnetic series.
Hence, the correct answer to the question is Sound waves.
