Which tool is explicitly described as a hand tool or power tool?

• A. Router.
• B. Dovetail hammer.
• C. Scribing block.
• D. Surface plate.

Answer: (A)

Power versus manual operation is the key idea. A router is a motor-driven tool used to cut, groove, or shape edges, and in design and technology contexts it is explicitly described as a power tool. The other items have different roles—marking and measuring (scribing block and surface plate) or basic hand-tool use for assembly (hammer-like tools)—and aren’t described as a power tool. So the router fits the description of a hand tool or power tool most clearly.
