उत्तर
Sugar
Explanation:
Sugar acts as a preservative by creating an environment that is inhospitable to bacteria and mold. It does this by drawing out moisture through a process called osmosis, which dehydrates and inhibits the growth of microorganisms that can cause spoilage. This is why sugar is commonly used in making jams and jellies.
