• A. Plunge Router
• B. Utility Knife
• C. Rubber Mallet
• D. Biscuit Jointer

Answer: (A)

A router is the rotary power tool designed to profile edges and cut grooves in wood and wood composites by using interchangeable router bits. The plunge router fits this description best because it’s a router type that can start a cut in the middle of a workpiece by plunging the bit down, giving precise depth control for edge profiles or grooves. The other tools don’t match: a utility knife and a rubber mallet are manual tools with no router bits, and a biscuit joiner is meant for cutting slots to receive biscuits for joining boards, not for profiling edges or cutting grooves with router bits.
