Answer:
Gravitational potential energy .
Explanation:
The tendency of an object (a stretched rubber band or compressed spring) to return to its original shape on the application of force possess elastic potential energy.
When we lift an object against the force of gravity, the energy possessed by it is called gravitational potential energy . It can be given by the formula as follows :
E = mgh
Where
m is mass of an object, g is acceleration due to gravity and h is height.
Hence, the correct option is (a) "gravitational potential energy ".
