Answer:
Correct.
Step-by-step explanation:
If the cost of production of 4K televisions decreases then as a result this will increase the supply of 4K televisions and shifts the supply curve of 4K televisions rightwards.
At the same time, there is a unfavorable change in the consumer preference. Now, consumers prefer to watch television programs on their smartphones, tablets or laptops. This will shift the demand curve of 4K televisions leftwards.
Therefore, there is a fall in the equilibrium price level and the effect on equilibrium quantity is ambiguous because it depends upon the magnitude of the shifts of demand and supply curve.
