The answer is C: Writing a diary
Intrapersonal communication is the communication with one’s self. This type of communication may include self-task, visualization, acts of imagination and sometimes recall and memory. You sit down and write notes on a diary about events that happened in the past. What comes to mind? Sounds, sights, scents? This type of communication is taking place within the individual since he or she is alone and thinking to himself or herself.
