Three different stones \[P,\,\,Q\] and \[R\] of different weights are lifted from the ground level to different heights on different planets as given below:

P: A 250 g stone is lifted to 10 m on the Earth.

Q: A 800 g stone is lifted to 2 m on Saturn.

R: A 1kg stone is lifted to 1 m on Jupiter.

Which of the following statements is true? (Given that the acceleration due to gravity on the Earth, the Saturn and the Jupiter are \[10\,\,m\,\,{{s}^{-2}},\,\,15\,\,m\,\,{{s}^{-2}}\] and \[25\,\,m\,\,{{s}^{-2}}\] respectively).

A)  More energy is required to lift stone \[Q\] than stone\[P\].

B)  More energy is required to lift stone \[P\] than stone\[R\].

C)  Stone \[P\] and stone \[Q\] require the same amount of energy.

D)  Stone \[P\] and stone \[R\] require the same amount of energy.
