✅Explanation: Silage is a preserved feed made by packing and fermenting plant material in an airtight container. This process is carried out under anaerobic conditions, which means in the absence of oxygen.

📌Other Options Explanations:
-C. Pasteurization is a process used to kill harmful microorganisms in food and beverages.

🔑Key Points:
-Silage is forage, crop residues or agricultural and industrial by-products preserved by acids in the absence of air.
-Air is the biggest enemy of silage.
-Ensiling is the preservation of forage based on a lactic acid fermentation under anaerobic condition.
-The lactic acid bacteria ferment the plant sugars in the crop to lactic acid and to a lesser extent to acetic acid.
-The production of these acids reduces the pH of the ensiled forage which inhibits spoilage micro-organisms.
-However if ensiled under incorrect conditions, different and poorer quality fermentation can occur.
-And thus produces butyric acid, resulting in unpalatable and lower quality silages.
