The edge le:ngth of a soiid possessing cubic unit cell is `2sqrt(2)r` (structure I), based on hard sphere model, which upon subjecting to a phase transition, a new cubic structure (structure II) having an edge length of `(4r)/(sqrt(3))` is obtained, r where r is the radius of the hard sphere. Which of the following statements is true?

A

Density of the structure II is lower than structure I

B

Density of structure II is higher than structure I

C

The pore volume in structure I is 1.2 times higher than that of structure II

D

The pore volume of both the structures are equal
