The correct answer is B. A malignant tumor has the ability to spread to other tissues and to initiate tumors at secondary sites, whereas a benign tumor does not spread.

Explanation:

Benign tumor is a controlled overgrowth of cell which do not have the ability to invade other tissue or organs so being tumors do not spread to other organs. Therefore being tumor is usually not carcinogenic or dangerous for human life.

A malignant tumor is different from being a tumor as it has the ability to invade other tissues and organs. This property is called metastasis. As malignant tumor can spread to other organs and can invade different organs so they cause cancers in the patients. So the correct answer is B.
