Which one of the following solutions will have the highest conductivity?

Assertion: Electrical conductivity of copper increases with increase in temperature.
Reason: The electrical conductivity of metals is due to the motion of electrons.

Molar conductivities $(\Lambda ^o_m)$ at infinite dilution of $NaCl$,$HCl$ and $CH_3COONa$ are $126.4$,$425.9$ and $91.0 \ S \ cm^2 \ mol^{-1}$ respectively. $(\Lambda ^o_m)$ for $CH_3COOH$ will be .......... $S \ cm^2 \ mol^{-1}$.

The equivalent conductance at infinite dilution of a weak acid such as $HF$:

Limiting molar conductivity of $CH_3COOH$ (i.e.,$\Lambda^o_{m(CH_3COOH)}$) is equal to:

The equivalent conductance of $NaCl$, $HCl$, and $CH_{3}COONa$ at infinite dilution are $126.45$, $426.16$, and $91 \ \Omega^{-1} \ cm^{2} \ eq^{-1}$ respectively at $25^{\circ}C$. The equivalent conductance of acetic acid (at infinite dilution) would be:
