Answer:
The correct answer is letter "B": an increase in price and an increase in the quantity supplied.
Step-by-step explanation:
Shortages are the results of unmatched quantity supplied and quantity demanded. In such cases, by supply law, an increase in price would cost an increase in the quantity supplied. This will cause the quantity demanded to decrease thus as long as the quantity supplied increases and the quantity demand decreases there will be a point at which both of them will coincide at a certain price which will be the equilibrium point.
