Hey there!
Here is your answer:
The proper answer to this question is option C "benign".
Reason:
The only tumor out of the options that grows in one part of the body would be the benign.
Also...
Benign is not cancer, because cancer can usually spread through the body but benign only stays in one part of the body. They could be dangerous if it forms in your brain but its not often.
Therefore the answer is option C!
If you need anymore help feel free to ask me!
Hope this helps!
