Answer:
A. The demand for Blu-ray players would increase and the equilibrium price of Blu-ray players would increase.
Step-by-step explanation:
Complement goods are goods that are demanded together. An increase in demand for one good would lead to an increase in demand for the other good.
If the price of LCDs falls, the quantity demanded would increase. This would lead to an increase in demand for the players too. The increase in demand for the players leads to a rise in price of the players.
