What is a thin stick with a sharp point commonly referred to?

The correct answer is a term that describes a long, slender object designed for specific purposes, often used in various contexts that involve precision and distance. In this case, the term that fits the description of a “thin stick with a sharp point” is one that is typically associated with archery or projectile motion. An arrow features a pointed tip designed to pierce through targets, making it distinctly characterized by its sleek design, sharpness, and intended use for shooting.

While other options also contain sharp points, they do not fully encapsulate the essence of a "thin stick with a sharp point" used in the context associated with arrows. A pencil, though pointed, is generally not a stick but rather a writing instrument. A needle, while sharp and thin, is a shorter implement used for sewing rather than for a long-distance projectile. A spike typically denotes a broader and sturdier object used for grounding or supporting other structures. Thus, the choice that aligns best with the description given is the arrow.
