Answer:
C) The ratio of adult civilians employed outside the home rises.
Step-by-step explanation:
GDP is the value of a country's goods and services produced within a period. Productivity is a measure of how efficient and capable a person, machine or system is.
When a country's adult civilians travel out for job opportunities, it reduces the home country's productivity levels. Goods and services produced in a country will definitely depreciate in a drastical way. Adult citizens who have the experience and capacity to handle machines have left the country, leaving it in the hands of inexperienced labourers who would have to go through rigorous training before they can start handling machines. While that is happening, hours meant to be working and producing outputs are spent training labourers.
