A
3.6 $ \overset{\text{o}}{\mathop{\text{A}}}\, $
B
1.8 $ \overset{\text{o}}{\mathop{\text{A}}}\, $
C
1.27 $ \overset{\text{o}}{\mathop{\text{A}}}\, $
D
1.56 $ \overset{\text{o}}{\mathop{\text{A}}}\, $
Solution:
Atomic radius for bcc structure $ r=\frac{a\sqrt{3}}{4}=\frac{3.6\sqrt{3}}{4}=1.56\,\overset{\text{o}}{\mathop{\text{A}}}\, $
