A basic assumption of Freud's psychoanalytic theory is that:

A. Maturational: Maturational crises occur during life transitions or developmental stages, such as adolescence or retirement. The client’s response to a sudden loss does not fit this category.
B. Adventitious: Adventitious crises are caused by unexpected or external events, such as natural disasters or violent incidents. The sudden death of a partner fits this category, as it is an unexpected and external event impacting the client’s life.
C. Developmental: Developmental crises involve issues related to developmental stages and transitions. The client’s reaction to a sudden death is not related to developmental stages but rather to an unexpected loss.
D. Situational: Situational crises arise from specific, often unexpected events that disrupt an individual’s life, such as job loss or sudden illness. The sudden death of a partner is more accurately described as an adventitious crisis rather than a situational crisis.

A. Situational crisis: A situational crisis arises from specific, external events that disrupt an individual's normal functioning. Going off to college could be considered a situational crisis if it leads to significant stress or difficulty adjusting.
B. Unanticipated crisis: An unanticipated crisis refers to unexpected events that were not planned for. While going off to college might be unexpected, the term "unanticipated crisis" is less specific and not as fitting as "situational crisis."
C. Adventitious crisis: Adventitious crises are caused by events that are not part of the individual's daily life, such as natural disasters or major accidents. Going off to college does not fit this description.
D. Maturational crisis: A maturational crisis occurs as individuals face developmental transitions or changes (e.g., adolescence, leaving home). Going off to college is a developmental milestone and thus is considered a maturational crisis.
