Explanation:

• Unemployment is a situation in which individuals are ready and willing to work at the prevailing rate of wages but the individuals do not get work. Number of unemployed = Labour force - Work force.
•  National Sample Survey Organization (NSSO) defines employment and unemployment on the following activity statuses of an individual:

I. Working or being engaged in economic activity.
II. Being not engaged in economic activity and either making tangible efforts to seek ‘work’ or being available for ‘work’ if the ‘work’ is available and
III. Being not engaged in any economic activity and also not available for work. Hence, all the given activity status are correct.

• Persons in the category I and II above are called labour force.
• Persons in the category I are called the workforce.
