Nouns are words that name people, things, places,
animals, etc.
Option B: The word 'freedom' refers to the power or right to speak, act, etc. It's a noun since it names this power. Hence option B is correct.
Option A: 'Hate' is a verb that expresses an action. It's not a noun and hence A is wrong.
Option C is wrong because A: 'hate' is not a noun.
Option D is wrong because the answer lies in B.
