The correct answer is option 'D', which states that spongy or cancellous bone is present in vertebrae, ribs, skull, epiphysis of long bones, and it contains both Haversian canals and trabeculae, as well as red bone marrow.

Spongy or cancellous bone is one of the two types of bone tissue found in the human body, the other being compact or cortical bone. It has a porous and honeycomb-like structure, with numerous small spaces filled with bone marrow.

Below is a detailed explanation of each of the given options:

a) Haversian canals: Haversian canals are present in compact bone, not in spongy bone. They are small channels that run through the bone and contain blood vessels, nerves, and lymphatic vessels. They are responsible for the transportation of nutrients and waste products to and from the osteocytes (bone cells) located in the lacunae (small cavities) within the bone matrix. Therefore, spongy bone does not contain Haversian canals.

b) Trabeculae: Trabeculae are the branching bony spicules or struts that form the internal framework of spongy bone. They provide structural support and help to resist stress placed on the bone. The arrangement of trabeculae forms a network of interconnected spaces in the spongy bone, allowing for the diffusion of nutrients and waste products. Therefore, spongy bone contains trabeculae.

c) Red bone marrow: Red bone marrow is responsible for the production of blood cells, including red blood cells, white blood cells, and platelets. It is found in the spaces within the trabeculae of spongy bone. Red bone marrow is highly vascularized and rich in blood supply, which is essential for the production and maturation of blood cells. Therefore, spongy bone contains red bone marrow.

d) Both (2) and (3): As explained above, spongy bone contains both trabeculae and red bone marrow. Therefore, the correct answer is option 'D'.

In summary, spongy or cancellous bone is found in various locations in the body and it possesses a unique structure with trabeculae and spaces filled with red bone marrow. This type of bone tissue plays a crucial role in providing structural support, facilitating diffusion of nutrients and waste products, and producing blood cells.
