Answer: (C)

Verified step by step guidance

1. Understand the structure and function of epithelial tissue: Epithelial tissue is classified based on the number of layers and the shape of the cells. Simple epithelium has a single layer of cells, while stratified epithelium has multiple layers.
2. Learn the characteristics of squamous cells: Squamous cells are flat and scale-like in appearance, which allows for efficient diffusion and filtration processes.
3. Identify the term 'simple squamous epithelium': This refers to a single layer of flat cells, typically found in areas where substances need to pass through easily, such as the alveoli in the lungs or the lining of blood vessels.
4. Compare the options provided: Analyze each description to determine which matches the definition of simple squamous epithelium. For example, 'A single layer of column-shaped cells with cilia' describes simple columnar epithelium, not squamous epithelium.
5. Select the correct answer: Based on the definition and characteristics of simple squamous epithelium, the correct description is 'A single layer of flat cells.'
