Answer: A. All the factors land labor capital.
When a person pays for all the materials used to make fudge at the grocery, that individual is using capital to procure raw material.
When a process or a recipe is followed to convert the raw materials to fudge and when the fudge is sold door to door, labor is being used.
There must be a place where the raw materials are processed to make fudge, hence land is also being used.
