Final answer:
The stressors most controllable by time management and organization are everyday hassles, which include daily minor irritations that can accumulate and cause stress.
Step-by-step explanation:
The category that includes most of the stressors that can be controlled with time management and effective organization skills is everyday hassles. These are the minor irritations and annoyances that are part of our daily lives such as rush hour traffic, lost keys, and arguments with friends or family. Unlike major life events, major catastrophes, or environmental issues, everyday hassles tend to accumulate and can lead to significant stress if not managed properly. However, they are often within one's control to manage through various strategies such as prioritization of activities, stress management techniques, and maintaining a healthy lifestyle that includes a balanced diet, adequate sleep, and regular exercise.
