Answer:
Musical play
Explanation:
A musical play is the work presented in a theater that presents several songs inserted in the story and sung by the actors, however, these songs are interspersed with scenes without songs, but with the presence of dialogues. The opera, on the other hand, has no dialogues and the entire work, or most of it, is sung with the presentation of arias, recitatives and choirs.
"My fair lady" is a work that features dialogue scenes interspersed with music scenes, we can say that it is a musical play.
