To copy text using drag and drop, which of the following must you press and hold down while dragging the text to a new location?

To copy text using drag and drop, you need to press and hold down the Ctrl key while dragging the text to a new location. This action modifies the default behavior of the drag and drop operation, which ordinarily moves the text instead of copying it. By holding the Ctrl key, you tell the program that you want to create a duplicate of the text at the new location rather than just repositioning the original content. This function is particularly useful when you want to replicate information without losing the source text. The other options provided do not serve the same purpose during the drag and drop operation for copying text.
