Which statements is/are true about HCP and CCP lattice
(A) Number of tetrahedral voids are twice of octahedral holes
\( \mathrm{P} \)
(B) 12 tetrahedral and 6 octahedral voids are present in one HCP unit cell
W
(C) C.N. of HCP unit cell is 12
(D) If atom of tetrahedral voids displace into octahedral voids then it is Schootky defect.
