C) Clover feels frustrated at what has happened at the farm and at her inability to stop it.
Explanation:
" If she could have spoken her thoughts, it would have been to say that this was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race." Here she thinks of how she Could've spoken her thoughts and perhaps could've had an influence on the events, but now, she has lost hope, with no picture of the future with just terror and control everywhere. The other options don't really work with the text as the last sentence: "There was no thought of rebellion or disobedience in her mind." goes against A and she was for Old Major's beliefs, but is distraught that the society has gone completely away from what they were. Hope this helps, idk why the other answer is that from another question.
