Efficient formatting is crucial in word processing. The question asks for the tool that copies formatting from one text to another.

• The Format Painter is the correct answer.

• Style Copier is incorrect; while it describes the function, it is not the standard or recognized name for this feature in applications like Microsoft Word.

Therefore, for replicating formatting, the Format Painter is the precise tool.
