Correct answer
B. Salt plays the same role as sugar in jam.
Step-by-step solution
In the preparation of pickles, salt is added as a preservative. It draws out moisture from the food items through osmosis, thereby reducing the water activity and inhibiting the growth of microorganisms. Similarly, in the preparation of jams, sugar is added which also reduces the moisture content and prevents microbial growth. Thus, salt in pickles plays the same role as sugar in jams.
