What is significant about lomov and natalya's disagreement about oxen meadows? a. chekhov is establishing lomov and natalya as wealthy land owners. b. chekhov is revealing the similarities in lomov and natalya's characterizations. c. chekhov is developing the universal theme of conflict. d. chekhov is making a statement about the practice of marrying for land rather than love.

The correct answer is B. This is a farce that satirizes marriage, by depicting a scene of a marriage proposal where everything is at stake except for the marriage itself. Both Lomov and Natalya are parts of this social milieu and both of them have their say in it.
The correct answer isn't D, because Lomov and Natalya start their quarrel before she even finds out that he came to propose to her. Also, the correct answer isn't A; whereas Lomov and Natalya are members of the upper class of landowners, this is not the point of the scene. It is not even C, because Chekhov's universal theme is not a mere land dispute, but the problems in the very concept of marriage.
