Answer:
C). Inspire viewers to support the war effort by portraying the enemy as a cruel and unfair political force.
Step-by-step explanation:
Word-choice always plays a vital role in conveying the intended message effectively to the readers. It assists the author in enlightening the reader as well as portraying the desired idea in readers' minds to comprehend their understanding and response.
In the given poster regarding the British Commonwealth's destruction of Nazi Germany, the keyword 'tyranny' is employed by the author to 'encourage the viewers to support the war effort by presenting the enemy as brutal and inhumane.' The use of a descriptive word like 'tyranny' portrays the barbaric and devilish picture of the enemy in viewers' minds that would help the author in making them feel an anger and hatred towards the enemy and eventually gaining their support in the war. Thus, option C is the correct answer.
