Orwell uses an example and a quotation for evidence in this excerpt
Answer: Option 2.
Step-by-step explanation:
This passage has been taken from "Politics and the English Language" which was written by George Orwell. In this he gives an example of the post which he gets, and quotes the author's feelings to write as well as the first sentence that he reads.
The rest of the options are wrong because the passage does not include statistical, hypothetical or factual evidence. In fact, the letter deals with the the author's viewpoint on the Allies and Germany.
