Hint: Release of saliva in the mouth marks the beginning of digestion of food. Digestion of food begins in the mouth where larger molecules are broken down into smaller molecules with the help of enzymes found in saliva.

Complete Answer:
Saliva is a thick colorless liquid which is found in the mouth of humans and vertebrates. After eating food, the release of saliva is increased. The primary function of the saliva is to lubricate and moisten the food so that food tastes good and also can be swallowed easily.

Saliva also maintains the body's water balancing by creating an urge of thirst when the body is dehydrated. It also helps in reducing tooth decay. Saliva has an enzyme called salivary amylase which helps in breakdown of starch.

Let us analyze the options to find the correct answer.
Option A: Submaxillary and sublingual ducts are present on the floor of mouth under the front of tongue and under the tongue respectively. They secrete saliva in the mouth for the digestion of starch.Therefore, this is the correct option.

Option B: Gastric gland is the secretory unit of the stomach. They are found in different locations in the stomach.Therefore, this is the incorrect option.

Option C: Pancreas is an organ that is located in the abdomen of our body. It is a very useful organ as it converts the food into energy that can be used by the humans. It has exocrine (digestion of food) and endocrine function (regulates blood sugar level).Therefore, this is the incorrect option.

Option D: Gall bladder is a small pouch that is situated under the liver of the body. It stores bile juice which is produced by the liver. Therefore, this is the incorrect option.

Thus, the correct option is A) Submaxillary and sublingual glands.

Note: Salivary gland is an exocrine gland located in the mouth. There are three pairs of salivary glands found in the mouth namely parotid, submaxillary and sublingual located in the buccal cavity.
