• Both A and R are true, but R is not the correct explanation of A.

• Both A and R are true, and R is the correct explanation of A.

• A is true, but R is false.

• A is false, but R is true.

Answer 1

A is true, but R is false.

Explanation:

The assertion is true because compressions and rarefactions travel through the medium as a sound wave. The reason is false because the particles of the medium only vibrate about their mean positions; they do not continuously move forward with the wave.
