answer : option (1) abccbaabc...
it has given that void fraction of layering pattern = 0.26
so, packing fraction of layering pattern = 1 - 0.26 = 0.74
now packing efficiency = 100 × packing fraction = 100 × 0.74 = 74%
but we know packing efficiency of face centered cubic lattice (fcc ) is 74 %. hence layering pattern is face centered cubic lattice.
you know the arrange of FCC is ABCCBAABC....
therefore option (1) is correct choice.
