Which description fits a coronet leg marking?

A coronet leg marking is characterized by a white marking that extends from the coronet, which is the area just above the hoof, down to the hoof itself. This marking is typically narrow and can vary in length and width, but it specifically originates from the coronet. Its distinctiveness is due to its placement on the leg, offering a clear and identifiable feature for identifying horses. The other descriptions do not accurately capture the specific characteristics of a coronet marking. For instance, large patches of white covering the entire leg, small dotted marks on the fetlock, or markings only present on the hoof are definitions associated with different types of leg markings, such as socks or stockings, which are not related to the coronet marking.
