If potential energy of a body of mass m on the surface of earth is taken as zero then its potential energy at height h above the surface of earth is (R is radius of earth and M is the mass of earth) a)-GMm/(R+h) b)-GMm/(h) c)GMmh/R(R+h) d)GMmh/(h+2R) please provide a detailed solution

a)-GMm/(R+h)
b)-GMm/(h)
c)GMmh/R(R+h)
d)GMmh/(h+2R)

please provide a detailed solution

C)GMmh/R(R+h)
is the potential energy
We know, p.e. = mgh
here, put the value of g and u'll get the answer.
Hope this helps.
