Which of the following works have been authored by Thomas De Quincey?
A) Confessions of An English Opium Eater
B) The French Revolution
C) Hudibras
D) Autobiography
E) Suspiria De Profoundis
Choose the correct answer from the options given below:

The correct answer is A, D and E.

Let us analyze the works of Thomas De Quincey and verify which of the options listed in the question were authored by him:
1. A) Confessions of an English Opium-Eater: This is Thomas De Quincey's most famous autobiographical work, first published in 1821 in The London Magazine and in book form in 1822. It describes his laudanum addiction and its effects on his life.
2. D) Autobiography: Thomas De Quincey wrote extensive autobiographical sketches and essays, which were later collected and published as his Autobiographical Sketches (often referred to simply as his Autobiography) in the 1850s.
3. E) Suspiria de Profundis: Published in 1845, this is a collection of essays and prose poems that serves as a sequel to his Confessions of an English Opium-Eater. The title translates from Latin to "Sighs from the Depths."

Now, let us identify the authors of the other works mentioned in the question to see why they are excluded:
- B) The French Revolution: This famous history book, published in 1837, was written by Thomas Carlyle, not Thomas De Quincey.
- C) Hudibras: This is a mock-heroic narrative poem written by Samuel Butler in the 17th century (published in parts from 1663 to 1678), not Thomas De Quincey.

Therefore, since works A, D, and E were authored by Thomas De Quincey, the correct option is A, D and E.
