  3. C and D only

  4. A, B, C and D

Show answer
Correct Option: C
Explanation:
a. Ileum is the longest part of small intestine.
b. Bile duct and pancreatic duct open together into the duodenum as the common hepato-pancreatic duct which is guarded by a sphincter called the sphincter of oddi.
c. Ileocaecal valve is present at the junction of small intestine and large intestine.
d. Mechanical digestion and chemical digestion of food occurs in buccal cavity, stomach and small intestine.
a and b are wrong. c and d are correct.

  1. Smooth muscles

  2. Skeletal muscles

  3. Both (A) and (B)

  4. Cartilage

Show answer
Correct Option: C
Explanation:

Answer : 
i) The tongue is composed of skeletal muscle fibers and smooth muscle fibers. 
ii) Unlike the cardiac muscle or smooth muscle of the organs and digestive system, skeletal muscle can be willingly controlled. 
iii) This allows for the tongue's mobility. 
iv) The muscles that lace throughout the organ secure it to surrounding bones and create the floor of the oral cavity. 
v) Mucous membrane covers the skeletal muscle and protects the body from microbes and pathogens.
vi) While muscularis mucosa is composed of a layer of smooth muscle fibers.

So the correct answer is option C. Both (A) and (B).
