B) He is making fun of leaders who tell lies to their people.
Explanation:
In this passage, Orwell is making fun of the leaders who tell lies to their people. Orwell shows how Napoleon uses Squealer as a spokesperson, and how he is able to convince others to disregard the truth. Squealer speaks persuasively and uses complex words in order to alter the real story and convince the animals that Napoleon has their best interests at heart. This is a common strategy among dishonest leaders.
