Answer:

The correct option is a-cancer arise in cells that have alterations in genes

Explanation:

Cancer occurs when there is the alternations in a previously occurring normal gene. Mutations in this gene might cause events such as the over expression of these genes which might lead to cancer development.  Although cancer is inherited from one cell generation to the next, most cancers and the risk for cancer development are not inherited from one's parents; however, there are exceptions. Cancers can be inherited but majority of them arise randomly.
