$(I)$ Only $C$ react with $0.10\, M\, HCl$ to give $H_2(g)$
$(II)$ When $A$ is added to solution of the other metal ions, metallic $D$ is formed but not $B$ or $C$

$\Lambda _{C{H_3}COONa}^o =91.0\, S \,cm^2 /equiv.$
$\Lambda _{HCl}^o =426.2 \,S \,cm^2 /equiv.$
What additional information$/$quantity one needs to calculate ${\Lambda ^o}$ of an aqueous solution of acetic acid ?

${C_6}{H_5}Cl + 2NaOH\mathop {\xrightarrow{{200 - {{250}\,^o}C}}}\limits_{200\,atm} {C_6}{H_5}ONa + NaCl + {H_2}O$
