Correct answer
DA only

Step-by-step explanation

Applying the electrical neutrality principle in metal deficiency defect.

One A2+ is missing then two A2+ ions are converted into A3+ ion so 0.05 A2+ ion are missing and 0.05×2  A2+ ion are converted in A3+ ion so for each O2- ion total A2+ ion 0.85 and A3+ ion is 0.1.

Hence, A satisfies the condition.
