Random Access MAC protocols are:

$*$Efficient for low channel load since the collision probability will be less.

$*$Efficient for high channel load since the collision probability will be less.

$*$Efficient for low channel load since the collision probability will be high.

$*$Efficient for high channel load since the collision probability will be high.

$*$None is true.
