Final answer:
The part of the rope that is looped so that the ropes lie alongside each other in knot tying is called a bight. Bight is different from a loop, hitch, or splice.
Step-by-step explanation:
When tying knots, the part of the rope that is looped so that the ropes lie alongside each other is called a bight. The correct answer to the question is a. Bight. A bight is essentially a U-shaped bend in the rope where no crossing occurs, and it allows the ropes to rest parallel to each other. This is different from a loop, which is created when the rope crosses over itself, a hitch, which typically involves attaching the rope to another object, and a splice, where the strands of two ropes are interwoven to join them together.
