The correct answer is compact bone, which is characterized by a dense structure that features tightly packed osteons, also known as Haversian systems. These osteons are organized in a way that minimizes spaces within the bone tissue, thereby providing strength and support to the skeletal structure. This arrangement enables compact bone to withstand high levels of stress and is crucial for protecting organs and supporting the body.

In contrast, cancellous bone and spongy bone refer to the same type of bone tissue, which contains many spaces filled with bone marrow and is generally lighter and less dense than compact bone. Cancellous or spongy bone is designed for flexibility and to absorb shock, not to bear significant weight or resist compressive forces like compact bone. Cartilage, on the other hand, is a different type of connective tissue altogether, serving various functions such as providing support and cushioning between joints, but is not classified as a type of bone tissue.
