The answer is "A.real GDP rises and unemployment falls".
Expansion is the period of the business cycle when the economy moves from a trough to a pinnacle. It is a period when the dimension of business action floods and total national output (GDP) extends until the point when it achieves a pinnacle. A time of extension is otherwise called a financial recuperation.
An expansion is one of two essential business cycle stages; the other is contraction. The progress from development to withdrawal is a pinnacle, and the changeover from contraction to expansion is a trough.
