Verified step by step guidance

1. Understand that mental health disorders are typically characterized by symptoms that are persistent, significant, and impair an individual's ability to function in daily life.
2. Evaluate each option by considering the duration and impact of the symptoms described: temporary or brief symptoms are usually normal reactions to stress and do not necessarily indicate a disorder.
3. Recognize that 'temporary trouble sleeping before an exam' and 'brief periods of irritability' are common, short-term responses to specific situations and are not usually signs of a mental health disorder.
4. Note that 'occasional feelings of sadness after a stressful event' are also normal emotional responses and do not imply a disorder unless they become prolonged and impair functioning.
5. Identify that 'persistent and significant impairment in daily functioning' is the key indicator because it reflects ongoing difficulties that interfere with a person's ability to manage everyday tasks, which is a hallmark of mental health disorders.
