Which is a malignant bone lesion of the mandible?

Osteosarcoma
Fibroma
Lipoma
Chondroma

The correct answer is: Osteosarcoma

Osteosarcoma is a type of cancer that affects bone tissue and often presents as a malignant lesion on the mandible. This type of cancer is typically fast-growing and can cause pain and swelling in the affected area. Fibroma, lipoma, and chondroma are all benign bone lesions, meaning they are not cancerous. While they may still require medical treatment, they do not pose the same level of danger as osteosarcoma. Therefore, they are not the correct answer to this question.
