Answer: B. Two

Explanation:

During the first stage, your body starts relaxing and falling into sleep. This is the lightest stage of sleep. You can wake easily during this stage, and are not "fully" asleep.

During the second stage, your body deepens into it's sleep, your heart rate decreases, your body temperature decreases, and more. This is the stage that "represents the beginning of actual sleep" which is the answer to your question.

During the third stage, your body is in a deeper state of sleep. Your muscles relax further, your breathing rate slows, and more.

During the fourth stage, your heart rate and body temperature rise again. Your brain is a bit more active, and your muscles start to "wake up" slowly again.

Kobotan [32]

Some students feel distressed only in test situations. They might be said to suffer from Acute Stress.

Answer: Option B

Explanation:

Stress is your body's reaction to specific circumstances. It's abstract, so something that is distressing for you may not be unpleasant for another person. There is a wide range of sorts of stress and not every one of them is terrible. Stress can enable you to act rapidly in a crisis or help you comply with a time constraint.

Acute stress is the most widely recognized sort of pressure. It's your body's prompt response to another test, occasion, or request, and it triggers your battle or flight reaction.
