The correct option is

The preservative is any substance that is capable of inhibiting, retarding, or arresting the process of fermentation, acidification, or decomposition of food. Sodium benzoate and sodium metabisulphite are chemical preservatives. Sugar reduces the moisture content which inhibits the growth of bacteria which can spoil food.
