Important questions on Electrolytic Cells And Electrolysis

In electrolysis of NaCl when Pt electrode is taken then  is liberated at the cathode while with Hg cathode it forms sodium amalgam, because:

A
Hg is more inert than Pt
B
more voltage is required to reduce at Hg than at Pt
C
Na is dissolved in Hg while it does not dissolve in Pt
D
concentration of ions is larger when Pt electrode is taken
