It is a situation deliberately brought by the government to reduce unemployment and increase demand by going for higher levels of economic growth. Hence pair 1 is not correct.
Governments go for higher public expenditures, tax cuts, interest rate cuts, etc.
Fiscal deficit rises, extra money is printed at a higher level of growth, wages increase.
Stagflation
It occurs when inflation and unemployment both are at higher levels. Hence pair 2 is not correct.
It is a combination of high inflation and low growth.
When the economy is passing through stagnation and the government shuffles with the economic policy, a sudden and temporary price rise is seen in some of the goods.
Hyperinflation
This type of inflation is 'large and accelerating'.
It is when the prices of goods and services rise uncontrollably. Hence pair 3 is not correct.
In this inflation, not only the range of increase is very large but also the increase takes place ina very short span of time.
Such inflation quickly leads to a complete loss of confidence in the domestic currency and people start opting for other forms of money- gold, physical assets, etc.
