Which of the following best describes a decorative casket handle part?

The correct answer identifies a fundamental component of the decorative casket handle. The term "tip" refers specifically to the ornamental part that is situated at the end of the handle. This embellishment is designed not only for aesthetic appeal but also serves a functional purpose, enhancing the overall design of the casket while maintaining visibility and accessibility for those utilizing the handle.

The other terms, while related to handles, do not accurately represent the decorative aspect. The "bar" typically refers to the main support of the handle rather than its decorative features. "Plane" generally relates to a flat surface and does not specifically connect to handle design. "Grip," on the other hand, describes the part of the handle that one would hold, which may not necessarily have decorative elements. Therefore, "tip" distinctly captures the essence of a decorative casket handle part in terms of both function and design.
