B .

the radius of the earth is (8/6) of the moon

C .

the radius of the earth is (8/6) of the moon

D .

the radius of the moon in (6/8) of moon

gEgM=RE2GMERM2G(ME/8)=8RM2RE2              ....(i)

where the sunscripts M and E are for the moon and the earth respectively.

Given, gEgM=61                             .....(ii)

From (i) and (ii), we get
