In Harold Pinter's play The Birthday Party, the idea of having the birthday party is suggested by Goldberg, making option (2) the correct answer.
Here’s a breakdown:
Meg (1): Meg initially refers to it being Stanley's birthday, but she does not explicitly suggest the party. She is more focused on her usual maternal, somewhat doting behavior toward Stanley and her routine interactions.
Goldberg (2): Goldberg, one of the two mysterious visitors (the other being McCann), explicitly suggests the idea of throwing a party during the events of the play. This suggestion is part of the unsettling, manipulative actions he undertakes in the story, contributing to the surreal tension and ambiguous motives of the characters.
Lulu (3): Lulu is another character who interacts with the group, but she does not propose the idea of the party.
McCann (4): McCann is Goldberg's partner and primarily follows Goldberg's lead, not originating the suggestion of the party.
Goldberg's suggestion serves as a mechanism to heighten the disorienting and oppressive atmosphere of the play, making him the correct answer.
