• D. All the above

Answer 1

The correct option is D All the above

Preventing the growth of microorganisms as well as slowing the oxidation of fats that cause rancidity is referred as food preservation. Food is preserved and flavored by the inclusion of combinations of salt, nitrates, nitrites, vinegar or sugar, with the desire of drawing moisture out of the food by the method of osmosis, this process is called curing. Acidic conditions also inhibit or stop microorganisms from growing or surviving i.e, submerging foods with vinegar or combination of vinegar and sugar helps to preserve food from microbial growth. Salt and sugar works together to increase osmotic pressure by destroying bacteria and lessening decay, boost the growth of useful bacteria and efforts together to promote taste.

So, the correct answer is option D.
