Solution

b
Stability of resonance hybrid $\propto$ no. of equivalent $R.S.$ So stability order is

$\mathop {\begin{array}{*{20}{c}}
O \\
{||} \\
{Me - S - {O^\Theta }} \\
{||} \\
O
\end{array}}\limits_{3 - eq.\,R.S.} $ $>$ $\mathop {\begin{array}{*{20}{c}}
O \\
{||} \\
{Me - C - {O^\Theta }}
\end{array}}\limits_{2 - eq.\,R.S.} $ $>$ $Me - {O^\Theta }$

So Acidic strength order is $x>y>z$ so $\mathrm{pK}_{\mathrm{a}}$ is $z>y>x$
