Two spherical bodies of same materials having radii $0.2 \, \text{m}$ and $0.8 \, \text{m}$ are placed in same atmosphere. The temperature of the smaller body is $800 \, \text{K}$ and temperature of bigger body is $400 \, \text{K}$ . If the energy radiate from the smaller body is $E$ , the energy radiated from the bigger body is (assume, effect of the surrounding to be negligible):

A
$256E$
B
$E$
C
$64E$
D
$16E$
