Which of the following is an example of a wood structural panel?

Wood structural panels are a category of engineered wood products that are made from wood-based materials and are used in various construction applications. These panels are designed to provide structural support and serve as sheathing for walls, roofs, and floors.

Oriented strand board (OSB) is a type of wood structural panel made from strands of wood that are layered in a specific orientation and bonded together with adhesives. This manufacturing process gives OSB excellent strength and load-bearing capabilities.

Plywood, another wood structural panel, consists of thin layers of wood veneer that are glued together in a cross-grain pattern to enhance its strength and stability. This arrangement helps minimize the risk of warping and cracking, making plywood a reliable choice for many construction applications.

Composite panels, which are typically made from a combination of materials, fall into a broader category and may not always be considered traditional wood structural panels as they can include non-wood components.

Since both OSB and plywood are examples of wood structural panels, and composite panels can sometimes comprise wood components, identifying all branches under the classification of wood structural panels confirms that "All of the above" is indeed the correct answer. This encompasses the various types of panels made primarily from wood-based materials.
