In metal excess defect, anions all missed from their lattice sites and they are occupied by electrons to maintain electrical neutrality. These sites occupied by electrons are called F-centers.

Solution

The correct option is B
Decreases

Density of crystal decreases due to this defect because anions miss from their lattice points and are occupied by very lightweight electrons.
