Solution:
(a) (i) Silver wire at will allow greater conduction of electricity because as temperature decreases, resistance decreases. Hence, conduction increases.
(ii) 0.1 M CH3COOH will allow greater conduction of electricity, because on dilution degree of ionization increases hence conduction increases.
(iii) KCl solution at will allow greater conduction of electricity, because at high temperature mobility of ions increases and hence conductance increases.
