Solution
The correct option is D Both vinegar and salt
∙ Preservatives are the substances that are generally added to kill or inhibit the growth of microorganisms in a food item.
∙ Common salt(NaCl) and sugar are natural preservatives, vinegar and sodium benzoate are chemical preservatives.
∙ Common salt removes the water content in the pickled mangoes. In the absence of water, bacteria can't multiply and hence it act as a preservative.
∙ Similarly, fishermen add salt to fish to keep them fresh for a longer period of time.
