A) Physical and chemical digestion occur in the mouth; only chemical digestion occurs in the small intestine.

Explanation:

Digestion is the biological process that occurs in the animals' bodies after or during their feeding. This process is important because it allows the nutrients and molecules that our body needs and are present in food to become assimilable and can contribute to the nutrition and health of our body. Digestion occurs through physical and chemical processes.

Physical digestion occurs in the mouth, through the grinding of food performed during chewing, however, chemical digestion also occurs in the mouth, due to the enzymes present in our saliva, which promotes the breakdown of some molecules.

Chemical digestion continues in the small intestine where nutrient assimilation occurs.
