Which sonnet is attributed to William Shakespeare?

Sonnet 18 is widely recognized as one of William Shakespeare's most famous sonnets. It begins with the iconic line, "Shall I compare thee to a summer's day?" and features the typical structure of a Shakespearean sonnet, comprising 14 lines with a rhyme scheme of ABABCDCDEFEFGG. Shakespeare's sonnets often explore themes of beauty, love, and the passage of time, making Sonnet 18 a quintessential example of his work in this genre.

The other choices represent works by different authors or in different styles: Paradise Lost is an epic poem by John Milton, The Raven is a narrative poem by Edgar Allan Poe, and A Dream Deferred is written by Langston Hughes. All of these works, while significant in their own right, do not belong to Shakespeare’s oeuvre. Therefore, identifying Sonnet 18 as the correct answer underscores its direct association with Shakespeare's contributions to English literature.
