48. Which knot in illustration D030DG represents a carrick bend?

Choice M is correct; it is the only illustration depicting two lines joined by the characteristic interwoven pattern of a Carrick bend. A Carrick bend is a bend, or knot used to join two lines, distinguished by its flat, symmetrical shape and alternating over-and-under crossings. Figures L, H, and J illustrate single-line knots or end treatments, not bends, and therefore cannot be a Carrick bend.
