A bereaved person's reaction comprising thoughts, feelings, and behaviors that changes over time is known as:

• A. Phases
• B. Mourning
• C. Mummification
• D. Grief

Answer: (D)

Grief is the internal, evolving reaction to a loss that involves thoughts, feelings, and behaviors and shifts as a person processes what happened. It goes beyond just sadness to include disbelief, anger, longing, guilt, and changes in daily functioning, and it unfolds differently for everyone over time. Mourning, by contrast, is the outward expression of that grief—the rituals, customs, and socially expressed behaviors. Phases or stages describe patterns some people experience, but they’re about the process people may go through, not the overall internal response itself. Mummification is not related to this concept. So the term that best fits the description is grief.
