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.

The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
The answer is because biology is easy and they're known around the world.
