Match List I with List II

List I		List II
A	Unicellular glandular epithelium	I	Salivary glands
B	Compound epithelium	II	Pancreas
C	Multicellular glandular epithelium	III	Goblet cells of alimentary canal
D	Endocrine glandular epithelium	IV	Moist surface of buccal cavity

Choose the correct answer from the options given below:

The correct option is A-III, B-IV, C-I, D-II.

Let us analyze each item in List I and match it with its correct counterpart in List II based on structural and functional characteristics of epithelial tissues:

A. Unicellular glandular epithelium matches with III. Goblet cells of alimentary canal.
Glandular epithelium consists of specialized cells for secretion. Unicellular glands consist of isolated single glandular cells. A classic example is Goblet cells of the alimentary canal, which secrete mucus to lubricate and protect the lining.

B. Compound epithelium matches with IV. Moist surface of buccal cavity.
Compound epithelium is multilayered (stratified) and has a limited role in secretion and absorption. Its main function is to provide protection against chemical and mechanical stresses. It covers the moist surface of the buccal cavity, pharynx, inner lining of ducts of salivary glands, and pancreatic ducts.

C. Multicellular glandular epithelium matches with I. Salivary glands.
Multicellular glands consist of clusters of cells working together to form secretory units. Salivary glands are a prime example of multicellular glands that produce and secrete saliva into the buccal cavity through ducts (exocrine glands).

D. Endocrine glandular epithelium matches with II. Pancreas.
Endocrine glands are ductless glands that secrete their products (hormones) directly into the fluid bathing the gland or into the bloodstream. The pancreas contains endocrine glandular epithelium in the islets of Langerhans, which secrete hormones such as insulin and glucagon directly into the blood.

Thus, by matching the columns, we get:
A → III
B → IV
C → I
D → II
