C. Elizabethan is the right option. The plays from this historic time, 1558- 1603 (XVI -XVII century), retell a historic story in five acts; in the original production , male actors played every role , including the women's roles and the stage directions contain minimal setting description. Shakespeare's plays are examples of this type of literary area.
A. Interregnum. This is not right because during this period, 1660-1688, theatre plays were illegal.
B. Modern. This is not right. The modern theatre includes both female and male members in the character lists. It does not refer just to history. The dramatic structure varies.
D. Postmodern. This is not right.The same as in B ,above, but this type of theatre also mixes up genres. It may include elements from the Medieval theatre and elements from a video game.
