Which of the following compounds can be $A$ ?
$A{l_{\left( s \right)}}|A{l^{ + 3}}\left( {0.1\,M} \right)||F{e^{ + 2}}\left( {0.001\,M} \right)|Fe\left( s \right)$ If $E_{A{l^{ + 3}}/Al}^o = - 1.66\,V$ and $E_{Fe/F{e^{ + 2}}}^o = + 0.44\,V$
$Pt(s)|\mathop {{H_2}(g)}\limits_{1\ atm} |HA\,\,\,\,\,\mathop {1\,M}\limits_{({K_a} = {{10}^{ - 7}})} \,\,||\,HB\,\,\,\,\,\mathop {1\,M}\limits_{({K_1} = {{10}^{ - 5}})}$
