Answer: (B)

Baseboard joints are the ways trim pieces along walls connect to each other and to corners. The typical set used for baseboards includes butt, miter, coped, and scarf. A butt joint is when the ends of two pieces meet end to end, a miter joint creates a clean corner by cutting the ends at angle joints, a coped joint is used to fit one piece against another, often around door casings or irregular shapes, and a scarf joint is used to join longer lengths for a seamless run. The other term groups refer to different kinds of woodworking joints (such as dado, rabbet, mortise-and-tenon, or tongue-and-groove) or to fasteners, which aren’t the standard baseboard joinery used in trimming walls.
