Answer:
B. Wagner's conception of opera.
Explanation:
Wilhelm Richard Wagner was a popular German composer in the<em> 1800s</em>. He was notable for the <em>musical phrases</em> he connected with his compositions. These were called "music dramas," which he became known for later in his operas.
For Wagner, such combination of music and drama in operas were ideally felt when he saw the performance of <em>Wilhelmine,</em> a dramatic soprano.
Wagner excelled more than the other composers when it came to<em> musical language. </em>This allowed him to take a huge role in influencing the classical music.
