Answer:
Option (a) is correct.
Explanation:
When the price of ground beef increases, this means that there is an increase in the cost of production of hamburgers because the beef is used as an input in the production of hamburgers.
So, an increase in the price of beef will result in a decrease in the supply of hamburgers because it will become less profitable for the suppliers and this will also shifts the supply curve leftwards.
Hence, this lower supply of hamburgers will cause the price of hamburgers to rise.
