The correct answer is: Contact with other cells inhibits their uncontrolled growth.
Contact inhibition as the word explains 'inhibition upon contact' is the property of normal cells. This mechanism regulates the cells to grow in one layer and thus uncontrolled growth is prevented. In cancerous cells this property is lost and this results in uncontrolled proliferation and tumor formation
