Correct Answer: (b) no cyclical unemployment
Solution:According to macroeconomics, full employment refers to the situation where the demand for labour at a given real wage level is equal to the available labour supply. The term is used for a situation where employment is generally found for all willing to work at the current rate of wages. Full employment is not a state of zero unemployment. Full employment does not mean that a person is not unemployed in the economy. In the state of full employment, there is a balance between employment opportunities and the people who are able and willing to do them, but in this equilibrium, some unemployment may be present in the economy, which is called 'Natural Unemployment'. According to Spencer, "Full employment is a situation in which everyone is working whatever they want to do, except those who are frictionally and structurally unemployed".
