because as the distance increases the gravitational force decreases so the weight of a body decreases
Answer:

Explanation:
We know that
Acceleration due to gravity g is given by the formula

G= gravitational constant
M= mass of the Earth
r= radius of the earth
Let acc. due to gravity after radius is 20% greater be g_2
then

=> g1/g2 = (r_2/r_1)^2 => g2 = 9.81/1.2^2 = 6.8125
A < B < C
C will increase faster than B which is faster than A
