Question
In general, cells go from being healthy cells to being cancer cells when:
Cells become more sensitive to density-dependent inhibition
A single mutation has removed the G1 checkpoint on the cell cycle
Multiple mutations have removed multiple checkpoints on the cell cycle
The cell cycle is stopped by a mutation
Cells are exposed to a carcinogen once
Cells become more sensitive to density-dependent inhibition

Multiple mutations have removed multiple checkpoints on the cell cycle

Cells are exposed to a carcinogen once
Explanation / Answer
Answer: Cells are exposed to a carcinogen once.
When healthy cells are exposed to carcinogens, mutations will arise. If these mutations continued in the daughter cells due to lack of check points, then cancer develops.
The other options are wrong because, if mutations are removed at any check points there won't be any cancer cells. The cell division of mutant cell will be stopped.
