Anglo-Irish relations in the 20th century have been represented in which of the following novels?
[A] Elizabeth Bowen – The last September
[B] May Sinclair – The divine fire
[C] JG farewell – Troubles
[D] J G farewell – The siege of Krishnapur
[E] Jeffery Farnol – Black Bartlemy’s treasure
Choose the most appropriate answer from the options given below:

The correct answer is A, and C only.

Let us analyze the works mentioned in the question to understand why they represent Anglo-Irish relations in the 20th century:

[A] Elizabeth Bowen – The Last September (1929)
This novel is set in County Cork, Ireland, during the Irish War of Independence (1919–1921). It depicts the lives of the Anglo-Irish gentry (specifically the Naylors at Danielstown) as their privileged, insular world faces destruction amidst the conflict between British forces and the Irish Republican Army (IRA). It is a classic representation of Anglo-Irish relations in the early 20th century.

[C] J.G. Farrell – Troubles (1970)
Note: The option text misspells the author's name as "JG farewell".
This novel is set in the fictional Majestic Hotel in Ireland during the Irish War of Independence (1919–1921). It illustrates the decay of the Anglo-Irish Protestant Ascendancy and the turbulent political climate of Anglo-Irish relations during this period. It won the Booker Prize (retroactively awarded as the Lost Man Booker Prize in 2010).

Let us look at the other options to see why they are incorrect:

[B] May Sinclair – The Divine Fire (1904)
This novel focuses on the life and artistic struggles of a young poet in London, rather than Anglo-Irish relations.

[D] J.G. Farrell – The Siege of Krishnapur (1973)
While written by the same author as Troubles, this novel is set in India and deals with the Indian Rebellion of 1857, not Anglo-Irish relations.

[E] Jeffery Farnol – Black Bartlemy's Treasure (1920)
This is a pirate adventure novel set in the 17th century and does not depict 20th-century Anglo-Irish relations.

Therefore, only novels [A] and [C] represent Anglo-Irish relations in the 20th century, making "A, and C only" the correct option.
