When improperly tied, which knot shown in illustration D030DG below is called a granny or thief's knot?

Correct Answer: Option D — W

A square knot, when improperly tied by crossing the ends incorrectly, results in a granny knot. This knot is notoriously unreliable, as it slips easily under load. A thief's knot is a variation that also lacks the security of a properly executed square knot.
