Answer:
B. Commercial farming.
Explanation:
Commercial farming is a type of farming usually on a large scale and it involves growing crops for economic activities or commercial purposes, by using modern farming technology such as modern irrigation methods.
The modern irrigation methods help to maximize water usage and boosts efficiency in agricultural production. The two modern methods of irrigation are;
1. Drip irrigation system: it is one of the most widely used and efficient irrigation system and it involves laying plastic pipes with holes around the crops, thereby allowing water to seep through the holes drop by drop.
2. Sprinkler irrigation system: it involves using a hose to distribute water to a specific section of the farm. The hose can be positioned at various strategic points to water crops just like a rain.
Also, commercial farming isn't limited to crop productions as it involves livestock farming too.
