The $K_a$ of monobasic acid $A, B$ and $C$ are $10^{-6}, 10^{-8}$ and $10^{-10}$ respectively. The concentrations of $A, B$ and $C$ are respectively. $0.1\,M$, $0.01\, M$ and $0.001\, M$. Which of the following is correct for $pOH$ of $A, B$ and $C$ ?
$pOH (A) < pOH (B) < pOH (C)$
$pOH (A) > pOH (B) > pOH (C)$
$pOH (A) = pOH (B) = pOH (C)$
$pOH (C) < pOh (A) < pOH (B)$
