Question

The correct option for the number of body centred unit cells in all 14 types of Bravais lattice unit cells is :

(1) 7

(2) 5

(3) 2

(4) 3

Answer 1

Correct option is (4) 3

In 14 types of Bravais lattices, body centred unit cell is present in cubic, tetragonal and orthorhombic crystal systems.

Hence, body centred possible variation is present in three crystal systems.

Answer 2

Correct answer is (4).

The number of Body centred unit cells in all 14 types of Bravais lattice unit cells is 3.

Answer 3

Among the 14 types of Bravais Lattices only 3 of them are Body Centred i.e., Cubic, Tetragonal and Orthorhombic. So, the correct answer is Opt. (4).
