The ratio of number of atoms present in a simple cubic, body centered cubic and face centered cubic structure are, respectively

The correct option is C $1:2:4$
Number of atoms in,
Simple cubic unit cell $=\frac{1}{8}\times 8=1$
BCC unit cell $=\frac{1}{8}\times 8+1\times 1=2$
FCC unit cell $=\frac{1}{8}\times 8+\frac{1}{2}\times 6=4$
The ratio of number of atoms in a simple cubic, FCC & BCC = 1 : 2 : 4
