hi there

In a body-centered cubic unit cell, there are two atoms per unit cell. Hence, from the expression r=N/a^3(M/Na)
We get, a^^3=N/ρ(M/Na)
=(2/10.3gcm^−3)x(95.04gmol^−1 /6.023×1023mol^−1)

=3.09×10^−23cm^3
or a=3.13×10^−8cm=313pm
Now since in the body centered cubilc unit cell , atoms touch each other along the cross diagonal of the cube , we have 4r=3a
 r=(√3a)(313pm)/4=135.5pm

so ans would be (3) 135.96
I have taken real value so approx ans...
