Pressing refers to the process of straightening hair using heat, often with a flat iron. When hair is fine and straight, it is already relatively flat and smooth, making it easier to achieve a smooth, straight result. Medium hair that is wavy may require more heat and effort to straighten, but it is still manageable. Thin and lightly curled hair may also be relatively easy to straighten. However, coarse and overly curly hair is the most challenging to straighten. It is thick, tightly coiled, and has a lot of volume, which makes it difficult for the heat to penetrate and straighten. Therefore, B is the correct answer.
