Question

A. Organic farming
B. Biotechnology
C. Seasonal food consumption
D. Permaculture

Answer

The correct answer is Biotechnology.

Explanation

The correct option is Biotechnology. Biotechnology is correct because it directly matches the approved learning objective to explain strategies to increase food supply including irrigation, aeroponics, hydroponics, the new green revolution, biotechnology and appropriate technology. This belongs to Food (optional route) within Section C: The challenge of resource management, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Food (optional route), reverse the geographical relationship, or make a broader claim than the objective supports.

Common mistake

Confusing Hydroponics and Aeroponics

Students often confuse hydroponics with aeroponics, thinking they are the same method of growing food without soil.

Remember that hydroponics uses nutrient-rich water to grow plants, while aeroponics suspends plants in air and mists their roots with nutrients.
