Correct answer will be option d)

Explanation:

  • By drying, water is removed from food substance. water is required some degree for enzymatic activity of microorganism. without water, microbes cannot survive.
  • By drying ,food is preserved for longtime by preventing microbial growth.
  • Pickling drops the pH level of food below 4.5 which is low enough to kill off most bacteria and thus used in food preservation
  • Main ingredient for murabba making is sugar. By creating a high concentrated sugar solution, a high osmotic  pressure is created. when microbes placed in such hypertonic solution water moves out from microbes. shrinkage and killing of microbes take place.
  • so by murabba food can be preserved for long time.
