Answer:
C Housing prices in Country A will increase as wood imports become more expensive.
Step-by-step explanation:
Since country A imports all wood from other countries, an increase in price of wood by suppliers means that they are now expensive. Country A will be paying much more money for the same amount of supply they imported before prices rose. This will lead to housing prices to increase as a way to pass over the costs to homebuyers and tenants through rising home prices and rents respectively.
