Final answer:
Fredrico is most likely in the anger stage of Elisabeth Kübler-Ross's five stages of grief, where individuals feel their situation is unfair and express frustrations. This stage follows initial denial and precedes the stages of bargaining, depression, and acceptance.
Step-by-step explanation:
Based on the description of Fredrico's behavior, he is most likely in the anger stage of Elisabeth Kübler-Ross's five stages of grief. At this stage, individuals often feel that their situation is unjust and may express their frustrations by being tense and critical, as Fredrico is displaying. This is consistent with Kübler-Ross's model where after an initial phase of denial, individuals come to confront their diagnosis with feelings of anger regarding the perceived unfairness of their impending death.The correct order of the stages in Kübler-Ross's model, as outlined in her seminal book On Death and Dying, is denial, anger, bargaining, depression, and acceptance. It is important to keep in mind that the process is not necessarily linear and that individuals can move between stages non-sequentially, and not all individuals will experience every stage.Understanding Kübler-Ross's five stages of grief can help individuals empathize with those in late adulthood or who are terminally ill, as it provides insight into the various emotional responses that come with confronting mortality.
