Option C) An enzyme in her mouth broke down the polysaccharides in the cracker into monosaccharides.
<h2>

- This happened because of saliva present in the mouth.
- Saliva is a watery substance which is present in our mouth and secreted by salivary glands. Saliva is composed of 98% water and it contains important substances like electrolytes, mucus, antibacterial compounds and various enzymes.
- The enzyme present in saliva is amylase which helps in breakdown of some starches(polysaccharide) into maltose(diasaccharide) and dextrin. Which means, digestion of food occurs within the mouth, before the food reaches the stomach.
Result: The result come positive due to the action of saliva on cracker.
