Solution

Here,       a=b≠c

And,        α=β=90°,     γ=120°

Every unit cell is structured as follows

 In the bottom layer the central atomic surrounded by six other identical atoms.

In the middle layer at height c/2 three atoms are positioned.

In the top layer,at height C atomic distribution is similar to that of the bottom layer.

Concept: Study of characteristics of unit cell of Diamond, ZnS, NaCl and HCP;
  Is there an error in this question or solution?
