To access the last style sheet in the object collection document.styleSheets, we need to use the syntax document.styleSheets[document.styleSheets.length-1]. Here, document.styleSheets.length will return the total number of style sheets in the document, and we need to subtract 1 from it to get the index of the last style sheet. Therefore, option C is the correct syntax to reference the last style sheet.
