What does 'environs' refer to?

The term 'environs' refers to the surrounding area or environment, particularly the regions that are adjacent to a particular place, such as a city or town. This word is often used in geographical contexts to describe the neighboring areas that are influenced by or connected to a central location. It encapsulates the idea of the outer area that surrounds a main site, which aligns perfectly with the correct answer.

In contrast, the first choice focuses on just the main urban center rather than its surrounding areas, while the third choice refers to an inner space, which does not capture the essence of 'environs.' The fourth option is about specific living quarters but does not relate to the broader concept of surrounding areas. The correct interpretation hinges on understanding that 'environs' encompasses those adjacent outer areas rather than just a central location or any inner environment.
