The number of lattices having only one Bravais lattice is

Of the three cubic Bravais lattices, primitive (P), body-centred (I) and face-centred (F), of elements, answer the following questions.

The number of lattices having only one Bravais lattice is three

The term "Bravais Lattice" describes the 14 various three-dimensional arrangements that atoms may be put in crystals. The smallest collection of atoms with symmetrical alignment that may be repeated in an array to form the full crystal is referred to as a unit cell.

Hence option C is correct
