Antonio Is a Wonder to His Local Community: at 91

Antonio is a wonder to his local community: at 91 he still lives in his own house, drives his car, and mows the lawn. However, he is slowing down a little-he occasionally gets home visits from extramural nurses, and regularly takes Meals on Wheels, but independently proclaims that this gives him a little "socialization." Which of the following terms best describes Antonio's lifestyle?

A) independent living
B) semi-independent living
C) self-care
D) self-efficacy
