Food is renewable resource due to:

Explanation

Food is considered a renewable resource primarily because of continuous photosynthesis, which allows plants to convert sunlight into energy, produce food, and support life on Earth. This natural process ensures that plants, which form the base of most food chains, can constantly produce food. Options A, B, and D refer to techniques and methods that enhance food production but do not inherently make food renewable. Mechanical forming prepares land for cultivation, improved crop varieties increase productivity, and pest control protects crops, but none of these address the natural regenerative process of photosynthesis.
