The type of milk that can last for several months without spoiling if it is unopened and unrefrigerated is Ultra High-Temperature Pasteurized milk.
The correct answer is Ultra High-Temperature Pasteurized milk. This type of milk undergoes a special pasteurization process that involves heating the milk to a very high temperature for a short period of time, killing off any bacteria or microorganisms that may cause spoilage. As a result, UHT milk can stay fresh and safe to consume for several months without the need for refrigeration, as long as it remains unopened. However, once the UHT milk is opened, it should be refrigerated and consumed within the same timeframe as regular pasteurized milk.
