Solution

The correct option is A True
In the case of an ideal single fixed pulley the effort needed is equal to the load itself and so the mechanical advantage is equal to 1.
As the amount of effort required is equal to the load itself so a single fixed pulley cannot be used as a force multiplier.
Hence, the given statement is true.
