Step 1: Understanding the Concept:
This question tests the understanding of factors affecting production in agriculture. Factors can be classified as internal (controllable by the farmer) and external (outside the farmer's control).
Step 2: Distinguishing Internal and External Factors:
Let's classify each factor:
• Internal Factors: These are factors that are within the control of the farmer or the farm management. They are also known as controllable factors.
_ _ _ _ Examples: Selection of the farm, choice of crops, use of inputs, management practices, etc.
• External Factors: These are factors that are outside the control of the farmer. The farmer cannot change or influence these factors.
_ _ _ _ Examples: Market prices, weather and climate, government policies, international trade conditions, pest and disease outbreaks.
Step 3: Analyzing the Options:
• (A) Market prices: External. The farmer cannot control the market price of inputs or outputs.
• (B) Selection of the farm: Internal. The farmer decides where to establish the farm, which is a management decision.
• (C) Weather: External. The farmer has no control over weather conditions.
• (D) Government policy: External. The farmer must operate within the policy framework set by the government.
Step 4: Final Answer:
Selection of the farm is NOT an external factor; it is an internal factor. Therefore, option (B) is correct.
