Solution

The correct option is C Assertion is correct but Reason is incorrect
To lift weight vertically we have to apply force equal to its weight or more while on ramp we have to apply force equal to component of weight of body or more along inclined plane which is always less than weight of body.

So lifting a load vertically requires greater efforts than to roll the same load up the ramp.

Also work done in lifting vertically is also more.
