Step 1: Understanding the Concept:
This question tests basic resource allocation principles and standard production function notations in agricultural economics.
Step 3: Detailed Explanation:
Let us analyze each statement:
- Statement (I): The fundamental economic question "How to produce" refers to the choice of technology and input combinations (e.g., labour-intensive versus capital-intensive), which is governed by the factor-factor relationship (finding least-cost combinations). The question of "what level of inputs to apply" corresponds to "how much to produce" (factor-product relationship). Thus, Statement (I) is incorrect.
- Statement (II): In production function notation, the variables written before the slash symbol ($X_1, X_2$) represent the variable inputs whose quantities can be adjusted in the short run. The variables written after the slash ($X_3, X_4, \dots, X_n$) represent the fixed inputs that are held constant. Statement (II) states the opposite, claiming that $X_1, X_2$ are fixed and the rest are variable. Therefore, Statement (II) is incorrect.
Consequently, both Statement (I) and Statement (II) are incorrect.
Step 4: Final Answer:
Both Statement (I) and Statement (II) are incorrect, corresponding to option (B).
