Which epithelium type is described as a single layer of mostly columnar cells with possible squamous or cuboidal cells?

Cell shape and layering are the key clues. A single layer with predominantly tall, column-like cells describes columnar epithelium, where the cells are long and arranged in a single row. The other options don’t fit as well: simple cuboidal would be a single layer of cube-shaped cells, not columnar; compound (stratified) epithelium would have multiple layers; ciliated epithelium refers to the presence of cilia rather than the overall columnar shape. So the description points to columnar epithelium.
