b. Tongue, Pancreas, Small intestine, Gallbladder and Salivary Glands.
c. Tongue, Small intestine, Large intestine, Gallbladder and Salivary Glands.
d. None of the above.

Answer 1

Hint: The accessory organs are those organs which aid in the process of digestion but are not considered as the part of the alimentary canal.

Complete answer:
The digestive system in humans comprises some main organs and other such organs which help in the process of digestion but are not directly involved in the digestive process and are known as accessory organs. The accessory organs play a key role in the digestive procedures. The main digestive organs are buccal cavity, esophagus, stomach, small intestine, large intestine and anus. The accessory organs that are associated with the digestive system are tongue, pancreas, liver, gallbladder and salivary glands. The accessory organs either secretes several enzymes or store the different types of substance that passes through digestion. These organs together facilitate the process of the digestive system by secretion of various enzymes and chemicals required during the process of digestion.

Hence, the correct option is a.) Tongue, Pancreas, Liver, Gallbladder and Salivary glands.

Additional information:
The accessory organs in the digestive system are those organs which may not be directly involved in food digestion but they have an equally important role to play in the entire process of digestion. The salivary glands help to keep the mouth and other parts of the tract moist by providing a required amount of saliva. Tongue helps the food to distribute evenly into the mouth for better grinding and chewing making the food easier to pass down. Pancreatic juice produced by the pancreas produces enzymes, which break down sugars, fats, and starch. The liver and gallbladder produces and stores bile juice respectively.

Note: The organs in the digestive system can be divided into two parts, main and accessory organs. The main organs are those from where the food moves through, while from the accessory organs the food is not digested directly. However, both the types of organs contribute equally in the process of digestion and absorption of food.
