Answer 2

The correct option is (4). Using file card.

• The file card is used to keep a file safe and dirt-free to secure it for a long time. It is a kind of equipment that is used in woodwork, plastic work, or in metalwork.
• A file card is used for detaching small items of any object from a place of work. Cutting or objects and any other sludge of sticky stuff becomes filled up in the teeth of files.
• The file card brushes have wires that are bent over and that show the direction for how we have to use them over any file.
