What would you call a process in which individuals may become cut off from full involvement in the wider society?

Social exclusion

The correct answer is Option (3) → Social exclusion

"Social exclusion refers to ways in which individuals may become cut off from full involvement in the wider society. It focuses attention on a broad range of factors that prevent individuals or groups from having opportunities open to the majority of the population. In order to live a full and active life, individuals must not only be able to feed, clothe and house themselves, but should also have access to essential goods and services such as education, health, transportation, insurance, social security, banking and even access to the police or judiciary. Social exclusion is not accidental but systematic – it is the result of structural features of society."
