Answer

To determine which substances can preserve foodstuff, let's analyze each option provided in the question:

1. **Understanding Preservation**: Preservation is the process of preventing food spoilage by inhibiting microbial growth. This can be achieved through various methods, including the use of preservatives.

2. **Analyzing Each Option**:
- **Option (a) Sugar and vinegar**: Both sugar and vinegar are known to help in food preservation. Sugar can create a hypertonic environment that draws moisture out of food, while vinegar, being acidic, can lower the pH and inhibit microbial growth.
- **Option (b) Salt and sugar**: Salt is a traditional preservative that draws moisture out of food, while sugar, as mentioned earlier, also helps in moisture control. Together, they can effectively prevent spoilage.
- **Option (c) Vinegar**: Vinegar alone is a strong preservative due to its acidity, which can prevent the growth of bacteria and fungi.
- **Option (d) All the above**: Since all the substances mentioned (sugar, vinegar, and salt) have preservative qualities, this option suggests that all of them can preserve foodstuff.

3. **Conclusion**: Since all the options listed (sugar, vinegar, and salt) are effective in preserving food by preventing microbial growth, the correct answer is **(d) All the above**.
