Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A crow bar has a special design. In it, the pivot is between the point of effort and load. In a crowbar the fulcrum remains farther distance from effort than load. So, the required effort to lift a load is respectively less.
But without any special structure
any machine can't be used as a
force multiplier.
