The statement is true because style refers to the unique set of characteristics that distinguish an artwork and can be used to identify the artist, the historical period, the school of artists, or the nation it belongs to. These characteristics can include techniques, subject matter, use of color, composition, and other elements that are consistent throughout the artist's body of work or prevalent in a particular time period or artistic movement. By analyzing the style of an artwork, art historians and critics can gain insights into its origins and influences.
