Correct Answer: Functional distribution .

Solution : The correct option is Functional distribution .

The theory of functional distribution is another name for the study of factor pricing. Based on the many components of production's individual contributions, this theory examines how the overall income produced in an economy is distributed among individuals. Because it deals with the functional roles that various elements play in the production process, it is known as a "functional" distribution. Contrastingly, "personal" distribution, which is concerned with how income is allocated across people or households, is different from this.
