Final answer:
To extract a digital file, one should use a computer program designed for file extraction or decompression. However, if the context is about a physical task, tools such as a power drill or socket wrenches would be suitable.
Step-by-step explanation:
When extracting a file, the most appropriate tool to use is C) Using a computer program. The other options, such as using a wrench, a knife, or a vacuum cleaner, are not suitable for this task as they are meant for physical manipulation of objects and cannot interact with digital files. You would typically use software specifically designed for this purpose, like a file extraction or decompression program, which can handle various file formats like .zip, .rar, or .7z. The process generally involves selecting the file you wish to extract and then using the program to unpack its contents into a specified directory on your computer.
If the context instead refers to a physical task that needs a tool, such as assembling furniture or making repairs, then power drill or socket wrenches would be good tools to have. A power drill is versatile for drilling holes and driving screws, while socket wrenches are ideal for tightening or loosening nuts and bolts.
