D. Women worked all kinds of jobs traditionally held by men.
Explanation:
During World War 2, the American conscription system only allowed adult males to be conscripted into war. This meant many businesses had suffered a major decrease in employment. This was replaced by women who were not conscripted and they had occupied the jobs of factory workers, nurses, mechanics, etc.
I believe that Hernando Cortés built Mexico City. (Hope this helps you! Feel free to message me if you have any further questions. :) Hope you have a nice day!!)
