Correct option is B)

Force of attraction between the earth and the object when an object is at the distance $a$ from the center of the earth.

$F=x_{2}GmM $

Consider the $dW$ is the small amount of work done in bringing the body without acceleration through the very small distance $dx$

$dW=Fdx$

And total work done to bring the body from infinity to point $p$ which is at distance $r$ from the center of the earth.

$w=∫_{∞}x_{2}GmM dx=−rGMm $

Hence, the gravitational potential energy $=−rGMm $
