Final answer:
Option B best describes phase IV of Caplan's phases of crisis, as it shows Carter struggling with depression and hopelessness after a tornado, aligning with Caplan's framework of the reorganization phase post-crisis.
Step-by-step explanation:
The question asks which of the provided options describes phase IV of Caplan's phases of crisis. In Caplan's framework, phase IV is characterized by the reorganization phase, in which an individual attempts to find solutions and might resort to new means of solving the problem after previous efforts have failed. Based on the details provided about Carter's reactions to the crisis, option B, where Carter comes to the crisis clinic complaining of depression and expresses that he does not want to go on living, is the closest to describing phase IV of a crisis according to Caplan's theory.
This is because it illustrates the potential outcome of an unsuccessful attempt to cope with the crisis, leading to feelings of hopelessness and depression.
