options:

• epithelial tissue; simple cuboidal epithelium
• dense connective tissue; dense regular connective tissue
• dense connective tissue; elastic tissue
• epithelial tissue; simple columnar epithelium

Explanation:

1. First, identify the tissue type: The tissue has a single layer of cells (simple) with cube - shaped cells (cuboidal), which is characteristic of simple cuboidal epithelium, a type of epithelial tissue.
2. Eliminate connective tissue options: Connective tissues (like dense connective) have different structures (more extracellular matrix, different cell arrangements) than the epithelial - like arrangement seen here.
3. Differentiate from simple columnar: Simple columnar has column - shaped (tall and narrow) cells, while the cells here are more cube - like. So the correct option is the one with epithelial tissue and simple cuboidal epithelium.

Answer:

epithelial tissue; simple cuboidal epithelium
