Which specifications are most likely for a family home of an elderly couple?

The selection of installing lever handles for all doors and rocker light switches, with the option of using illuminated ones in select areas, aligns closely with the specific needs of an elderly couple living in a family home. Lever handles are easier to operate than traditional doorknobs, as they require less hand strength and dexterity, which can be particularly beneficial for individuals with limited mobility or arthritis.

Rocker light switches follow the same principle of accessibility; they are generally easier to operate than standard toggles, especially for those who may have difficulty using fine motor skills. The provision of illuminated switches can also enhance safety during nighttime or low-light conditions, helping to prevent accidents and make navigation easier.

While options such as installing handles that are easy to grasp, using brighter bulbs, and installing nightlights are beneficial considerations in creating a safe home environment for the elderly, the comprehensive approach of option D addresses multiple aspects of accessibility and safety. This option ensures that the physical environment is specifically tailored to reduce challenges faced by elderly residents, promoting independence and comfort within their living space.
