A
One of the best overall “indicators” of a healthy or unhealthy city is air quality. This is because air pollution levels are typically low in well-planned cities with good transport systems, walkable streets and ample green spaces to filter the air. And air pollution levels soar in urban settings that prioritize road transport over pedestrians and cyclists, and that allow uncontrolled sprawl in large, grey, unbroken blocs of asphalt and concrete.

People live in cities to be close to employment and educational opportunities and services, and cities can be wonderful places for social interaction and access to cultural activities. When cities are built using good planning principles, they can also be communities that foster health and well-being. Think of the cities or the neighbourhoods that you have particularly enjoyed living in or visiting – and how such places looked, felt or even "smelt".

Air quality is poorest in WHO’s Eastern Mediterranean and Southeast Asia regions, followed by Africa.

The inference talks about two main points- i- most of the people in the world breathing low quality air. ii- health problems caused because of low quality air. In option 3, both these are discussed. Option 1 talks about urban space and air pollution. Option 2 talks about cities and pollution. Option 4 talks about safety of health workers.
