While I don't have the capability to view images, I can provide context based on the time period. The cover of the Saturday Evening Post in 1922 likely illustrates significant social developments of that era.
If the images depict themes related to women's rights, such as women's roles in society, suffrage, or changes in social behavior (like fashion or workplace integration), the most fitting answer would be:
D. the growing influence of the women’s rights movement.
On the other hand, if the images highlight cultural aspects related to immigration, such as celebrations of diverse cultures or influences brought by immigrant populations, then the answer could align with:
B. the growing cultural influence of immigrant populations.
Without seeing the actual images, I cannot definitively select an answer. However, you can consider the content and themes of the illustrations to make the most informed choice.
