Which of the following terms does not refer to informal settlement types?

The term that does not refer to informal settlement types is public transport. Public transport encompasses systems and services designed to transport individuals in urban areas, including buses, trains, and subways. It is a structured and regulated aspect of urban infrastructure aimed at facilitating mobility and accessibility for residents.

In contrast, terms like favelas, shanty towns, and cage homes specifically refer to informal settlements where individuals may reside in inadequate housing conditions, often lacking official recognition and access to basic services such as sanitation, clean water, and electricity. These informal settlements typically arise in response to rapid urbanization and economic challenges, highlighting the contrast with organized public transport systems.
