Which of the following tools is used to drill holes on wooden blocks?
Answer: D
A ratchet brace holds a bit and is turned by hand with a ratchet action, so it can be used to drill holes in wooden blocks even where there is little room to turn it a full circle, since the handle can be moved to and fro. A spanner is used to turn nuts and bolts, a hacksaw cuts metal and pincers grip or pull out nails and wire. So the tool for drilling holes in wood is the ratchet brace, option (D). The bit is held in the chuck of the brace and the sweep of the handle gives the turning force, so the worker can bore holes of a fairly large size in wood by hand.
