Christaller's Central-Place Theory is based on which two principles of the following ? 
A. Range of Goods
B. Threshold
C. Marginal influence
D. Functional influences
Choose correct option :

Accepted Answer

Christaller's Central-Place Theory is indeed based on the principles of **Range of Goods** and **Threshold**. Therefore, Option 1 (A and B) is the correct answer.

Here's why:

*   **Range of Goods (A):** The range of a good or service refers to the maximum distance a consumer is willing to travel to purchase it. This is a crucial element in Christaller's theory because it determines the market area of a central place. Goods with a higher range will be offered in larger central places that serve a wider area.

*   **Threshold (B):** The threshold is the minimum population or demand required to support the provision of a particular good or service. A central place must have a sufficient population within its market area to meet the threshold for the goods and services it offers. This determines the minimum size and function of a central place.

Together, the range and threshold determine the size, spacing, and hierarchy of central places.

Now, let's explain why the other options are incorrect:

*   **Option 2 (A and C):** While the range of goods (A) is correct, "Marginal influence" (C) is not a core principle of Christaller's Central-Place Theory. The theory focuses on the overall demand and market area, not the marginal impact of individual consumers.

*   **Option 3 (B and D):** While the threshold (B) is correct, "Functional influences" (D) is too broad and not a specific, defined principle within the core framework of Christaller's theory. While the functions of a central place are important, the theory is more directly based on the quantifiable concepts of range and threshold.

*   **Option 4 (C and D):** Neither "Marginal influence" (C) nor "Functional influences" (D) are fundamental principles upon which Christaller's Central-Place Theory is built. The theory is more directly concerned with the quantifiable concepts of range and threshold.

Therefore, Option 1 (A and B) is the only option that accurately identifies the two core principles upon which Christaller's Central-Place Theory is based.
