Which of the following plays of Shakespeare is not a comedy?

Option 4 : Antony and Cleopatra

The correct answer is Antony and Cleopatra.

• Antony and Cleopatra is a historical tragedy by William Shakespeare written sometime after the ascent of King James I to the throne of England.
• It was first performed in the Globe Theatre in 1607, but was only officially published, like most of Shakespeare's other works, in the Folio edition of 1623.
• It is a play concerning the tragic love story between the Roman general Antony, who was part of the Second Triumvirate with Augustus Caesar, and Cleopatra, the legendary Queen of Egypt. 

•  Critics have often disagreed on the subject of the classification of Antony and Cleopatra; some have called it exclusively a history play, though there are many differences in the play's plot with verified historical accounts, while some have also classified it as a romantic comedy.
• However, with Antony and Cleopatra both dying by the end of the play, it can definitely be classified as a tragedy, though it does not follow the rules of an Aristotelian classification. 
• Shakespeare's powers of character building shine bright in this play, as he invests both Cleopatra and Antony with exquisite grandeur and highlights the tragic nature of their love story.

Hint

•  As You Like It, Twelfth Night and A Midsummer Night's Dream are all well-known romantic comedies by Shakespeare, and the student should not face much difficulty in eliminating those options from consideration.
