Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R).\n **Assertion (A):** The velocity of sound in a gas increases with an increase in temperature.\n **Reason (R):** With an increase in temperature, the density of the gas decreases and the average kinetic energy of the gas molecules increases, leading to faster transmission of vibrational energy.\n Select the correct answer using the codes given below:

Options:

• A: Both A and R are true and R is the correct explanation of A.
• B: Both A and R are true but R is not the correct explanation of A.
• C: A is true but R is false.
• D: A is false but R is true.
