The backbone of the ship is referred to as the ______.

• A. Hull
• B. Deck
• C. Keel
• D. Stern

Answer: (C)

The keel is often referred to as the backbone of a ship because it serves as the primary structural element that runs along the bottom of the ship from the bow to the stern. It provides the necessary support for the vessel’s structure and is crucial for the overall stability and strength of the ship. The keel also helps in determining the ship's shape and affects its performance in water, playing a significant role in the ship's resistance to lateral forces while sailing. In contrast, while the hull is the outer shell of the ship that provides buoyancy, the deck refers to the upper covering or floor of a ship, and the stern is the rear part of the vessel. These components are vital for the ship’s functionality, but they do not provide the same foundational structural role that the keel does, which is why the keel is termed the backbone.
