Answer: 4. Mutations inhibit production of telomerase.

Cancer cells show reactivation of telomerase, which keeps telomeres from shortening and makes the cells immortal. So the statement that mutations inhibit telomerase production is not true.

The other statements are true: proto-oncogene mutations speed up the cell cycle, loss of telomerase inhibitor raises telomerase activity, and mutations switch off normal cell-cycle control.
