Who among the following was not associated with the Movement Poetry?

The correct option is Charles Kingsley.

To understand why this is the correct answer, we can look at the literary movements associated with each of the figures listed:
1. The Movement (or Movement Poetry) was a term coined in 1954 by J. D. Scott, the literary editor of The Spectator, to describe a group of British writers who rejected the romanticism, surrealism, and modernist experimentation of the 1930s and 1940s. Instead, they favored anti-romanticism, rationality, irony, and traditional poetic forms.
2. Key poets and writers associated with The Movement include Philip Larkin, Kingsley Amis, Donald Davie, Elizabeth Jennings, John Wain, Thom Gunn, and D. J. Enright. Therefore, Davie, Jennings, and Wain were active members of this mid-20th-century group.
3. Charles Kingsley (1819–1875), on the other hand, was a prominent Victorian novelist, poet, and cleric. He lived and wrote during the 19th century, long before The Movement emerged, and is widely known for his novels like Westward Ho! and The Water-Babies, as well as his association with Christian Socialism. Thus, he was not associated with Movement Poetry.
