B) Time and the Conways
C) The Silver Tassie
D) The Countess Cathleen
E) The Plough and the Stars
Choose the correct answer from the options given below:

The correct option is A and D only.

To understand why this is the correct choice, let us analyze each of the plays listed in the question:

• A) The Land of Heart’s Desire: This is a Irish play written by the renowned poet and playwright William Butler Yeats (W. B. Yeats) in 1894. It is a poetic play that explores Irish folklore and themes of the fairy world.
• B) Time and the Conways: This play was written by the English dramatist J. B. Priestley in 1937, not by W. B. Yeats. It is well-known for its exploration of theories of time.
• C) The Silver Tassie: This is a tragicomic play written by the Irish playwright Seán O'Casey in 1927. Yeats notoriously rejected this play for performance at the Abbey Theatre.
• D) The Countess Cathleen: This is another famous verse play written by W. B. Yeats. Published in 1892 and first performed in 1899, it served as the inaugural production of the Irish Literary Theatre.
• E) The Plough and the Stars: This is a highly significant drama written by Seán O'Casey, first performed in 1926, which deals with the Easter Rising in Dublin.

Therefore, among the choices, only A (The Land of Heart’s Desire) and D (The Countess Cathleen) were written by W. B. Yeats, making A and D only the correct answer.
