Answer : 1. "epithelium"
Explanation :
The tissue that forms glands is:
(A) Epithelium
Explanation:
Epithelial tissue is responsible for the formation of glands. Glands are structures that produce and secrete substances such as hormones or enzymes. Epithelial cells can be organized to form glandular tissues, and glands can be classified into two main types: exocrine glands and endocrine glands. Exocrine glands release their secretions through ducts, while endocrine glands release hormones directly into the bloodstream. Epithelial tissue plays a crucial role in the formation and function of both types of glands.
