Solution
The correct option is C 12 There are 12 nearest neighbors to a given lattice point in a FCC lattice. We say that the coordination number of a lattice point in the FCC lattice is 12. The distance of the nearest lattice point in terms of the lattice parameter (i.e, the edge length of the cubic unit cell) is a√2
