During and After the 16^th Century, Many Factors Changed the Way

During and after the 16^th century, many factors changed the way in which the self, the individual and social groups were conceptualised. For instance, people started to become mobile in order to seek work. As a result, they needed to have a portable personal identity rather than one embedded in a social structure that was based purely on their geographically fixed extended family. This is referred to as:

A) secularisation.
B) industrialisation.
C) enlightenment.
D) mobilisation.
