Solution
The correct option is AFeO
In metal deficiency defect, a cation is missing from its lattice site. To maintain electrical neutrality, one of the nearest metal ions acquires an extra positive charge. This type of defect occurs in compounds where the metal can exhibit variable valency. e.g., Transition metal compounds.
In the given options, an only metal which exhibits variable valency is Fe.
