Which of the following could indicate a shift in self-concept for an individual?

Graduating from college can significantly impact an individual's self-concept, as it often represents a major life transition and achievement. This milestone can enhance a person's self-esteem and confidence, reflecting their ability to set and accomplish goals. Such achievements contribute to the development of a positive identity, reinforcing self-worth through accomplishment. The new identity associated with being a college graduate can shift how an individual views themselves in relation to their aspirations, social roles, and professional opportunities.

While adopting a pet, changing jobs, and moving to a new city are also impactful life events, they may not necessarily lead to a fundamental shift in self-concept in the same immediate way that a graduation might. Each of these experiences can influence self-perception and identity but might not carry the same weight of achievement and societal validation that coming to the end of a college career does.
