# Explanation:<br />## Step 1<br />The problem is asking us to identify the classification of an instrument that produces sound by a tightly stretched membrane. The options provided are idiophone, chordophone, aerophone, and membranophone.<br /><br />## Step 2<br />Idiophones are instruments that produce sound from the vibration of the material of the instrument itself, without the need for strings, membranes, or columns of air. Examples include bells and cymbals.<br /><br />## Step 3<br />Chordophones are instruments that produce sound from the vibration of strings. Examples include guitars and violins.<br /><br />## Step 4<br />Aerophones are instruments that produce sound from the vibration of air. Examples include flutes and trumpets.<br /><br />## Step 5<br />Membranophones are instruments that produce sound from the vibration of a stretched membrane. Examples include drums and tambourines.<br /><br />## Step 6<br />Given the description in the problem, the correct answer is D. Membranophone, as it is the classification for an instrument that produces sound by the vibration of a tightly stretched membrane.<br /><br />: <br />D
