1. Contact inhibition is a property of normal cells.
2. It is not a property of cancer cells.
3. Due to this property, normal cells remain in contact with other cells inhibiting their growth.
4. None of the above.

Correct answer: Due to this property, normal cells remain in contact with other cells inhibiting their growth.

Solution

Contact inhibition means normal cells stop dividing when they touch neighboring cells, which prevents overgrowth. Cancer cells typically lose this control, so the option describing inhibited growth in normal cells is correct.
