Accepted Answer

Lyophilization is the process of freeze-drying food, which involves removing moisture from the food under low temperature and pressure. This method is used for long-term preservation of food without compromising its nutritional quality, taste, and texture. Therefore, option D is the most suitable choice. Other options such as A, B, C, and E involve different preserving methods such as acidification, canning, sun-drying, and salting, respectively, which are not the same as lyophilization.
