A) Falling prices for goods are usually caused by a lack of production or avaliability.

Explanation:

When the resources to make a good are limited or there are fewer producers in the market to make that good, prices will go up. This is because there is less competition, which means the supplier is going to put the highest price on their good knowing that other options are limited or non-existent.
