“The Princess: A Medley” by Tennyson is

The correct option is A Narrative Poem.

Alfred, Lord Tennyson's The Princess: A Medley, published in 1847, is a seriocomic narrative poem written in blank verse.
A narrative poem is a form of poetry that tells a story, often making use of the voices of a narrator and characters as well.
The work tells the story of a heroic princess who foregoes the world of men to found a women's university, and the prince who seeks to win her love by infiltrating the university disguised as a woman.

Although it contains famous lyrical interludes (such as "Tears, Idle Tears"), the overall structure, plot development, character progression, and storytelling format categorize the work as a narrative poem rather than a lyric, an elegy, or a dramatic monologue.
