Given below are two statements, one labelled as Assertion (A) and the other labelled as **Reason (R):** Assertion (A):** Auditoriums designed for musical concerts generally have curved ceilings and sound-absorbing materials on their walls. **Reason (R):** Sound-absorbing materials reduce reverberation time, while curved ceilings help in spreading sound evenly across the hall. 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
