• B. Less reverberation
• C. Both $A$ and $B$
• D. None of these

Answer 1

Answer: (A)

Sound is absorbed by the curtains

We hear more clearly in a room with curtains than of that in a room without curtains because curtains act as a good sound absorbent. So, they absorb the sound produced in the room and thus, prevent unwanted echo of sound due to refraction. Otherwise, the inter lapping of sounds would be most undesirable as we won't be able to hear clearly.
