Answer: a. hassles
Step-by-step explanation:
Regular stressors and inconveniences are known as hassles and these can potentially add up to stress. Types of stressors vary on their timescale, and are classified into acute or chronic.
Acute stressors are caused by brief events such as being robbed at gunpoint but the effects can be felt much longer than the actual event. Chronic stressors, on the other hand is a result of an event that occurs over a longer period, such as caring for a terminally sick relative.
