Answer:
a. Dark and mysterious moods along with suspense
Step-by-step explanation:
Gothic literature is a literary strand that represents the Romanticism most directed towards the mystery and the dark side. It deals, above all, with themes that contradict the customs, traditions and culture of a given society.
Edgar Allan Poe is considered the father of Gothic literature in the United States and highly praised as a poet. His works are as attractive today as they were more than a century ago. Creative and brilliant, with a penchant for nighttime themes, and a demonic tone behind every page, their stories and poems are still shocking and surprising. Poe became a literary sensation in 1845 with the publication of the poem 'The Raven', considered a great literary work and one of the best of Poe's career, where he explored some of his themes, death and loss.
