Solution

The correct option is C Impermeable and dead
A plant cell is characterized by a well developed cellulosic cell wall which is dead at maturity and consists lignin. Since cell wall is dead at maturity it does not take part in any physiological or biochemical process and may not allow passing molecule across it. Therefore, the correct answer is option C.
