Answer:
A group of colleagues.
Step-by-step explanation:
A stressor is any environmental event, experience, or stimulus that causes stress on an individual. These events or experiences are perceived as threats or challenges to the individual and may be physical or psychological in nature. How an individual responds to a stressor can be affected by many factors and can influence how stress will affect their body.
A group of colleagues is not part of the factors that influence how an individual responds to an extressor.
