C. Limited
If you have a small amount of product/resources that means that it is rare, and therefore more valuable.
For example, in the U.S. economy, there is a limited amount of currency, and that is what makes the currency valuable.
Or the better example, in a game like Minecraft, the resource "diamond ore," is only worth value to the player because it is a Limited resource, and it does not spawn often.
Hope this helps!
