$\huge\boxed{ANSWER:-}$

BRAVIS showed the geometry of crystal as 14 different ways.

➡️ According to Bravis there are 14 possible three dimensional lattices.These are called Bravis lattice

Following are the cherecteristics of crystal lattice:-

• each point in a lattice is called lattice point or lattice site.

• Each point in a crystal represents one constituents particles (may be atom, molecular or ion)

• Lattice points are joined by straight line to bring out geometry of lattice.

$\boxed{option\:4\:is\:correct}$
