Which is not the part of business cycle?

Boom
Depression
Recovery
Acceleration

The correct answer is D. Acceleration.

A business cycle is a period of time during which the economy experiences alternating periods of growth and contraction. The four phases of a business cycle are expansion, peak, contraction, and trough.

  • Expansion is the period of time when the economy is growing. During this time, businesses are hiring more workers, producing more goods and services, and making more profits.
  • Peak is the point at which the economy reaches its highest level of activity. After this point, the economy begins to contract.
  • Contraction is the period of time when the economy is shrinking. During this time, businesses are laying off workers, producing fewer goods and services, and making fewer profits.
  • Trough is the point at which the economy reaches its lowest level of activity. After this point, the economy begins to expand again.

Acceleration is not a part of the business cycle. It is a term used to describe a period of time when the economy is growing at a faster rate than usual.
