Correct answer
0.928

Step-by-step explanation

Let us assume, the crystal has fcc or ccp lattice which has octahedral voids.

Number of lattice sites occupied = 8 corner + 6 face centres = 14

Number of octahedral voids = 12 edge centres + 1 body centre = 13

Number of octahedral void(s) per lattice site
