The glands of vertebrates are derived from invaginated epithelium.

Here's a step-by-step explanation:

1. Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue, and nervous tissue. It lines the cavities and structures throughout the body, and also forms many glands.

2. The process of gland formation begins with the growth of epithelial tissue. This tissue then invaginates, or folds in on itself, to form a pocket.

3. As this pocket deepens, it pinches off from the surface epithelium and forms a gland. This is why we say that glands are derived from invaginated epithelium.

4. The other options provided - stratified, scarified, and endocrine - are not correct. Stratified refers to the arrangement of cells in layers, scarified is a process of scratching or cutting the surface, and endocrine is a type of gland that secretes hormones directly into the blood.
