The correct options are A) everyday language and B) commonplace characters. As a modern realist, Ibsen's concern were ordinary people, the kind we meet each day, the kind we are. Hedda Gabler is just one of those many women who have wasted their lives in boring marriages, with partners they don't love, doing things they don't enjoy. There are no spectacular stage props - the action takes place in an absolutely ordinary setting. Language isn't grandiose and figurative because characters aren't that either.
