Which class is Sleeping?

• A. Class D
• B. Class A
• C. Class B
• D. Class C

Answer: (A)

In this classification system, states are grouped by levels of activity or responsiveness. Sleeping is the most inactive, restful state, so it is placed in the class that represents rest or inactivity. That’s why sleeping falls under Class D. Think of Class D as the label for when there's no active engagement—just rest. The other classes are tied to levels of wakefulness or action, so they don’t describe sleeping.
