Scientists have conducted multiple experiments on cancer cells to determine how they reproduce. all
studies have shown the same result. choose the correct response that explains the results
cancer cells reproduce every second and are impossible to control
cancer cells contain stem cells and continue to differentiate, making it difficult for the body to stop
reproducing the cancer cells
o cancer cells lack contact inhibition; therefore, they do not stop reproducing

I’d say the last one, the cancer cells lack inhibition and the do not stop reproducing. The rest of the answers don’t really make sense. The cancer cells can be controlled with chemotherapy so the first one is definitely wrong. And I do not believe that they contain stem cells. The last one is right because the reason cells become cancerous is because their growth inhibitors are broken or switched off, so they do not know when to stop growing and it becomes a problem for the body.
