Solution

## The correct option is A fcc > bcc > pcExplanation for correct option(A)fcc > bcc > pcPacking efficiencyPacking efficiency is the percentage of total space filled by the particles.The packing efficiency of a face-centered cubic lattice is $74%$.The packing efficiency of a body-centered cubic lattice is $68%$.The packing efficiency of the simple cubic lattice is $52.4%$.So, the order of packing efficiency order is as follows:-fcc > bcc > pcExplanation for incorrect optionThe packing efficiency of the face-centered cubic (fcc), body-centered cubic (bcc), and simple primitive cubic (pc) lattices follows the order fcc > bcc > pc. Hence, options (B), (C),and (D) are incorrect.Hence, option (A) is correct. The order of packing efficiency is fcc > bcc > pc.
