Answer:
The correct answer is osteoclastoma.
Explanation:
Osteoclastoma refers to a benign bone tumor generally featured by massive damage to the epiphysis of the long bone in adults. It is most commonly witnessed in the knee, that is, at the distal femur and the proximal tibia. The tumor is usually surrounded by new bone development and may develop briskly.
The condition may limit movement and can result in pain. Generally, the treatment is done by surgery and is called a giant cell tumor of bone. The tumor is diagnosed with the help of radiography, in which it appears as large bubbles distinguished by thin bone strips.
