The apparent coefficient of expansion of a liquid when heated in a copper vessel is $C$ and when heated in a silver vessel is $S$. If $A$ is the linear coefficient of expansion of copper, then the linear coefficient of expansion of silver is
$\frac{{C + S - 3A}}{3}$
$\frac{{C + 3A - S}}{3}$
$\frac{{S + 3A - C}}{3}$
$\frac{{C + S + 3A}}{3}$
