Answer:
D. All of the above
Explanation:
Film is a recorded movie and it will always be the same, no matter what or how many times you watch the film because there is no constant change.
Theatre, however, is sometimes a constant change, there are understudies that need to be filled in and that understudy gives off a different vibe than the originally casted member in the show. There might be accidents, etc. Audience will always change as well since it almost a different show each time, say for instance today the performance was great, but tomorrow, they need an understudy to cover and it gives a different vibe. Every person casted in the show is usually comfortable with who has usually played in the show the most and constantly interactive and there are no "CUT!" or any redos, and have to continue on with show.
Not sure about the 1st one, but it sounds like a cruel irony, or karma, where one does something bad, and later on the same bad thing gets done to you. Breaking the fourth wall is when a character in a comic, book, or tv show/movie talks to the reader, or states that he knows that there is an audience and he is just a character (comes from the old tv sets where there were only 3 walls, and the fourth wall was where the audience would watch in, and cameras would shoot: so when they "broke the fourth wall", they looked out at the audience and talked to them). Externalised conscience is essentially, as far as i know, when a character decides between what he wants to do and what he should do, and there are usually many soliliquies (excuse the spelling) while he makes the decision. Not sure if this is all 100% correct, but that's what my non-drama knowledge allows me, and hope it helps you out a little bit.
