Given :
Assertion
A lemon crusher is a 2ndnd order lever.
Reason
In a 2ndnd order lever, effort arm is greater than load arm.

Solution :
A lever that has the load between the fulcrum and the effort is known as a second order lever. And the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever. And the lemon crusher satisfies the given defination.
The Correct Opt=A
