Answer:
The answer is A)change in the aggregate price level.
Explanation:
A supply curve is a graphical illustration of the relationship between the amount of a commodity that a producer or supplier is willing to offer with respect to the price of goods at any given time. Â
It is the graphical representation of a supply schedule.
In a graph, the price of the commodity is shown on the vertical axis and the quantity supplied is shown on the horizontal axis. Â
The higher the price, the higher the quantity supplied, the lower the price, lesser will be the quantity supplied and can e represented as movements in a supply curve.
The movement in supply curve can be an extension or contraction. Â
Extension in a supply curve is caused when there is an increase in the price or quantity supplied of the commodity while contraction is caused due to a decrease in the price or quantity supplied of the commodity.
A movement along the short-run AS curve occurs, holding everything else constant, when there is a change in the aggregate price level.
