The correct answer is C: elongated cells with thickening at the corners.
Collenchyma cells are characterized by their elongated shape and thickening at the corners. These cells have primary cell walls composed of cellulose and pectin, similar to other plant cells. However, collenchyma cells have additional localized thickenings in the cell corners, which provide mechanical support to the plant.
The thickened corners in collenchyma cells can vary in shape and appearance. They may appear as discrete spots, continuous bands, or even form a complete ring around the cell. The thickened areas contain extra cellulose and may also contain hemicellulose and lignin, which contribute to the cell's rigidity and strength.
The thickened corners of collenchyma cells allow them to provide flexible support to growing plant organs, such as stems and petioles. They help the plant withstand bending and mechanical stress while still allowing for some degree of flexibility.
