Solution

The correct option is A
near the end of the tube and keeping the other end closed

The reflected sound can be detected better by keeping one ear near the end of the tube and the other ear closed.
Because by doing so, other environmental sounds can be excluded and one can focus only on the sound coming from the tube.
Hence, the correct answer is an option (A).
