Explanation
The correct answer is (B). The mechanical advantage (MA) of the forklift is 4. This is calculated by dividing the output force (900 N) by the input force (225 N). The forklift multiplies the input force by 4 times to lift the crate. This means the forklift is four times more effective at applying force than without it.
