The correct answer is A. The actors over did the comic scenes in the play.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option B, The actors had over done the comic scenes in the play, implies that the actors did the comic scenes too much in the past, but they are not doing them too much now. Option C, The actors are over doing the comic scenes in the play, implies that the actors are doing the comic scenes too much now, but they may not have done them too much in the past. Option D, The actors over do the comic scenes in the play, is grammatically incorrect.
The sentence The comic scenes in the play were over done by the actors means that the actors did the comic scenes too much. This could be because they were trying too hard to be funny, or because they did not understand the material. Whatever the reason, the actors’ performance of the comic scenes was not successful.
