The best answer among the options provided is:
A. Soviet posters were less sophisticated due to the scarcity of experienced artists.
Soviet propaganda posters were often characterized by bold colors, strong messages, and a certain aesthetic that reflected the urgency and ideology of the time. While the artistic quality varied, the lack of experienced artists due to the political and social upheavals of the time did impact the visual sophistication compared to the more polished propaganda seen in some other countries.
The other options contain inaccuracies or mischaracterizations of Soviet propaganda motives and themes. Soviet propaganda was highly ideological, aiming to promote unity and bolster morale rather than criticizing leadership. While they often depicted women in strong roles, it wasn't necessarily reflective of them being portrayed as "less than men." Additionally, Soviet propaganda typically focused on a unified message in Russian rather than being printed in many languages like the propaganda from some other Allied nations which might have targeted diverse populations.
