Tumor suppressor genes typically inhibit division of cancer cells and preventing tumor formation.Mutation in this gene result in loss of function so it is typically recessive. This means that tumor suppressor genes acts as brake in formation of cancer cell. It prevents the growth of tumors. If one brake (one tumor suppressor gene) is defective it can still stop the car or cancer formation. However, since mutation in tumor suppressor gene is recessive, if two brakes are defective the car will not stop. Or the tumor will be expressed and be formed.

Correct answer: D). They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.
Cancer is uncontrolled growth of the cell in the body. The Old cell does not die and instead of that, they have grown out of control, which results in the formation of new abnormal cells. These may form a mass of tissue called a tumor.
Due to uncontrolled growth of a cell, the normal function of neighboring tissue or organ may be disturbed or it might damage vital organ such as kidney, heart, lung etc and may cause death.
