Answer:
C). The author defines the meaning of the word propaganda.
Step-by-step explanation:
The authors employ organizational structure to arrange the various elements of an essay or work along with its sub-ideas in a specific manner(sequential, problem-solution, cause-effect, etc.) in order to enhance its clarity and comprehension for the readers.
As per the question, option C i.e. 'the author defines the meaning of the word propaganda' most appropriately demonstrates that how the organizational structure has been employed in the given passage as the entire essay primarily aims to describe what does the word propaganda mean and its purpose.
The author describes that 'propaganda is anything....cause' which 'aims to influence the audience emotionally to turn their decision favorably and not offering them factual information'. The author also asserts that 'it helps in preventing people from thinking sensibly' however, he also says that 'it is not negative always'. Therefore, the entire passage organizes the meaning of 'propaganda' and different dimensions of its use/purpose. Thus, option C is the correct answer.
