The correct answer is: B. Distribution of Income among factors of production
In economics, distribution refers to the way in which income is divided among the factors of production: land, labor, and capital. The distribution of income is determined by a number of factors, including the productivity of the factors of production, the bargaining power of workers and employers, and government policies.
Option A is incorrect because it refers to the distribution of labor, which is not the same as the distribution of income. The distribution of labor refers to the way in which workers are divided among different occupations and industries.
Option C is incorrect because it refers to the distribution of capital, which is not the same as the distribution of income. The distribution of capital refers to the way in which capital is owned and controlled.
Option D is incorrect because it refers to the distribution of goods, which is not the same as the distribution of income. The distribution of goods refers to the way in which goods are made available to consumers.
