Step-by-step explanation:
A reader is most likely to experience a sense of horror while reading a work of Gothic horror. Gothic literature is known for its dark, mysterious settings and supernatural elements, aiming to evoke emotions of terror and unsettlement. Examples of this genre include Edgar Allan Poe's tales and Mary Shelley's Frankenstein, which contain ominous atmospheres, a feeling of dread, and themes related to death and decay. Authors like Ann Radcliffe specialized in creating eerie narratives, which often involve fear, as well as the grotesque and the sublime. The emotions readers may encounter also include suspense and a sense of the uncanny or the inexplicable, often due to the genre's preoccupation with the supernatural and the unknown.
