Answer:
B. Men played all the characters, both male and female
Explanation
Men played the role of both male and female in Greek theatres.
A male actor could play the role of three different people in one play. This was because of the role of the women in Greek culture which saw women as being inherently inferior to men and because of the importance of drama to the Greek, women were not allowed to participate in plays in any form so the males played all the roles that were available in a play.
Women in Greece then were seen to be lower than slaves, that's how low they were viewed in Greek society.
.
The Greeks considered allowing a female on set was too dangerous so they allowed men act all characters of a play.
