Which room category typically includes formal living rooms and family rooms?

The correct answer identifies the category that encompasses spaces where people gather for social activities and relaxation, typically featuring furniture like sofas and coffee tables designed for comfort and aesthetics. Living rooms are often one of the main areas in a home designated for entertaining guests or family gatherings, which is why they are specifically categorized in this manner. Family rooms may serve a similar purpose, offering informal spaces for leisure activities, further solidifying the importance of this room category in residential architecture.

In contrast, other room categories serve distinct functions that do not align with the characteristics of a living room. For example, an office room is designed primarily for work tasks, while a utility room is used for practical purposes, such as laundry or storage for cleaning supplies. Storage rooms, on the other hand, are specifically meant for keeping items that are not regularly in use, which further separates them from the social and leisurely aspects of living and family rooms.
