Step 1: When the picture shows two half-hitches thrown the same way so the strands cross and the knot looks twisted rather than flat, that is a granny knot. Step 2: Tying right-over-left twice (instead of alternating) gives this knot. Because the throws are not reversed, it loosens easily and is not recommended for ligatures. Step 3: The safer alternatives differ: the reef knot reverses the second throw to lie square and flat, and the surgeon's knot doubles the first throw for extra friction. Neither flat nor double-wrapped, the image is the granny knot. \[\boxed{\text{Granny knot}}\]
