Answer:
d. A business cycle is a major, prolonged fluctuation rather than a day-to-day movement.
Step-by-step explanation:
The business cycle, or as it is also known, the trade cycle, are a series of long ups and downs that occur to any nation market and it is formed by 4 stages:
Expansion
Crisis
Recesion
Recovery
This 4 stages can affect the personal finances of the common people, because each of this can last from a year to a decade, the great depression was the crisis of its trade cycle and it lasted a decade. A day-to-day movement can be perjudicial on a certain level, but a recesion is a bad prolongued period of financial struggle for all people, as well as expansion and good days.
