Answer:
The least likely symptom of stress among the options provided is D) appetite. Stress can affect individuals in various ways, and while appetite changes can occur as a result of stress for some people (such as increased or decreased appetite), it is generally not considered one of the most common or prominent symptoms.
The other options, stomach pain, sleeplessness (insomnia), and anxiety, are more commonly associated with stress. Stomach pain can be a result of stress-induced tension or digestive issues. Sleeplessness or difficulty sleeping is a common symptom of stress, as the mind is preoccupied or racing with thoughts, making it challenging to relax and fall asleep. Anxiety is closely related to stress and can manifest as feelings of worry, nervousness, or unease. However, it's important to note that individuals may experience stress differently, and symptoms can vary from person to person.
