The correct answer is a. tyler decided to give away toys, hoping it would give him more space.
"hoping it would give him more space." is an adverb clause for his reasoning behind it and is a clause that fulfills the purpose that you described. D doesn't' have a clause because it is a phrase, c is a phrase also, while b is a clause that is an adjectival clause.
The term comrade in Animal Farm is important because it means a friend who is also an equal, as the other answer notes. However, its main importance is its contribution to the allegory of the story. Comrade is the official title used among people in Communist countries such as the Soviet Union. Animal Farm is a metaphor for the rise of the Soviet Union, and so the term comrade is used by the animals to refer to one another.
