One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C). 
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation. 
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively. 
Normal cells are characterized by their ability to regulate cell division during the cell cycle. 
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.
