Question

Among $A l subscript 2 end subscript O subscript 3 end subscript comma S i O subscript 2 end subscript comma P subscript 2 end subscript O subscript 3 end subscript$ and $S O subscript 2 end subscript$ the correct order of acid strength is </span

$A l_{2} O_{3} < S i O_{2} < S O_{2} < P_{2} O_{3}$
$S i O_{2} < S O_{2} < A l_{2} O_{3} < P_{2} O_{3}$
$S O_{2} < P_{2} O_{3} < S i O_{2} < A l_{2} O_{3}$
$A l_{2} O_{3} < S i O_{2} < P_{2} O_{3} < S O_{2}$

The correct answer is:
$A l subscript 2 end subscript O subscript 3 end subscript less than S i O subscript 2 end subscript less than P subscript 2 end subscript O subscript 3 end subscript less than S O subscript 2 end subscript$
