I believe your answer is A. 1- non-confrontational, 2-cooperative, 3- confrontational, 4- confrontational and non-confrontational.
In Version 1, George walks past, with literally no confrontation at all, so that one is obviously non-confrontational. Already we see that one one option has 1 with non-confrontational, but we'll go through the rest as well, just to make sure they fit.
In Version 2, George seems to, at least for the most part, calmly talk to Elaine, and explain why he is upset. This feels much more cooperative than anything else.
In Version 3, George yells at Elaine, telling her to "shut up", before demanding his boss to tell him why he was being fired. That is very confrontational.
And finally, in Version 4, George demands to know where Elaine had heard that from, but she is calm about it, and tries to make a joke to lighten the mood. This is George being confrontational, but Elaine being non-confrontational.
All of these answers align with answer choice A. I hope I helped!
