The correct option is A
The song is the controlled emission of sounds of the human vocal apparatus (voice), following a musical composition. Singing also occupies an important place in music, because it is the only musical medium that can integrate text to the musical line. There are different singing techniques that are applied according to the musical style in which they are sung. In the opera, whose base comes from the motto "recite singing", the technique of lyrical singing is applied (the bel canto refers to the romantic style of Italian opera, from 1800-1900), while in the popular song the pattern is to achieve a sound similar to that of the spoken voice.
