Final answer:
The flag raised for the play Othello would have been the black version of the St. George's Cross, signifying that a tragedy was going to be performed in Elizabethan England.
Step-by-step explanation:
The play Othello by William Shakespeare would have raised the St. George's Cross, as it was performed during Elizabethan times, when this flag was used as England's national flag. The Union Jack was not created until the Acts of Union 1707, the Jolly Roger is typically associated with pirates, and the White Ensign is used by the Royal Navy. Theatres like the Globe, where Shakespeare's plays were performed, would raise specific flags to advertise the type of play being performed that day – a red flag for histories, white for comedies, and black for tragedies. Since Othello is a tragedy, a black version of the St. George's Cross would have been used.
