The change in the gravitational potential energy when a body mass \( m \) is raised to a height \( n R \) above the surface of the earth is (here \( R \) is the radius of the earth) [WB-JEE 2010]
(a) \( \left(\frac{n}{n+1}\right) m g R \)
(b) \( \left(\frac{n}{n-1}\right) m g R \)
(c) \( n m g R \)
(d) \( \frac{m g R}{n} \)
