What is a push factor that might cause immigration? a.) something that causes people to leave their country b.) any legal restriction on immigration c.) any hardship an immigrant faces in a new country d.) something that draws people to a new country

A.) something that causes people to leave their country

Push factors 'push' the immigrants from their home country to their immigranted family. Push factors can include war, famine, or other disasters. 

This is different from a pull factor, in which the pull factor pulls people to a better place, such as moving from a city to another for better working conditions or higher wages.

hope this helps
