Answer to Question 1

C

Answer to Question 2

Benign tumors are not cancerous. They are clumps of cells that are usually enclosed in a fibrous shell that prevents them from spreading. They are harmless unless they grow to the point of obstructing or crowding out normal tissues.
Malignant tumors are cancerous. They consist of abnormal cells that are usually not enclosed in a capsule, so they can spread to other areas of the body. Malignant cells invade surrounding tissue, disrupting normal cells. They can also seed the blood and lymph with malignant cells, which can then travel to form tumors at distant sites. This process is known as metastasis.
