What is not one of the four parts of an arrow?

The correct answer identifies "Quarrel" as not being one of the four main parts of an arrow. Traditional arrows consist of several key components that are essential for their function and performance.

The nock is the part of the arrow that fits onto the bowstring, allowing the arrow to be securely attached and released when the bow is drawn and shot. The fletching refers to the vanes or feathers on the back end of the arrow, which help stabilize its flight and ensure it travels accurately towards the target. The shaft is the long, straight body of the arrow, which provides structural integrity and houses the other components.

In contrast, "quarrel" generally refers to a type of projectile used in crossbows, often characterized by a flat, broadhead tip. This term is not applicable to traditional arrows used in archery with bows. Understanding these components is crucial for safe and effective archery, making it clear why quarrel does not belong in the categorization of parts of an arrow.
