Correct answer
B. salt plays the same role as sugar in jam
Step-by-step solution
In the preparation of lemon pickle, salt is added as a preservative. Salt increases the osmotic pressure and draws out water from the cells of microorganisms through osmosis, thereby inhibiting their growth and preventing spoilage. Similarly, in the preparation of jams, sugar is added in high concentrations. Sugar also acts as a preservative by reducing the water activity and causing plasmolysis of microbial cells. Thus, salt in pickles plays the same role as sugar in jams. Answer: salt plays the same role as sugar
