I gave my students this multiple choice question: Devil facial tumor disease (DFTD) is a disease that is decimating the population of Tasmanian devils. The disease passes from one animal to another through bites and is caused by parasites. The parasites cause cancerous tumors that spread throughout an infected animal's body and kill it. What is the best description of DFTD?

Only one answer is correct among these 4 choices:
- a non-infectious, cell-cycle disease
- an infectious, cell-cycle disease
- a non-infectious, chronic disease
- an infectious, chronic disease

Could you tell me which one is correct?

an infectious, cell-cycle disease
