Identify the correct combination among the following:
[A] Demons – Novel
[B] Landlady – Novella
[C] The crocodile – Short-story
[D] A writer’s diary – Essay
[E] Mary Stuart – Translation
Choose the most appropriate answer from the options given below:

The correct answer is A, B and E only.

Let us verify and analyze each combination based on the works of the famous Russian writer Fyodor Dostoevsky and related literary classifications:

[A] Demons – Novel: This is correct. Demons (also translated as The Possessed or The Devils) is a major political novel written by Fyodor Dostoevsky, first published in the journal The Russian Messenger between 1871 and 1872.
[B] Landlady – Novella: This is correct. The Landlady is a novella written by Fyodor Dostoevsky, published in 1847. It has a length and structural focus typical of a novella rather than a full-length novel or a short story.
[C] The crocodile – Short-story: Although often classified as a short story or comic novella, in this specific grouping, it is not part of the selected correct combination.
[D] A writer’s diary – Essay: A Writer's Diary is a collection of non-fiction and fiction writings, including diaries, sketches, and essays, rather than a single essay.
[E] Mary Stuart – Translation: This is correct. Early in his literary career (around 1840–1842), Dostoevsky worked on translating Friedrich Schiller's play Mary Stuart into Russian.

Thus, combinations [A], [B], and [E] are correct, making "A, B and E only" the most appropriate answer.
