Correct answer
See solution below.
Step-by-step explanation
Coordination number is the number of nearest neighbours of a central atom in the structure.
bcc has a coordination number of 8 and contains 2 atoms per unit cell.
This is because each atom touches four atoms in the layer above it, four in the layer below it and none in its own layer.
