During electrolysis of $NaCl$ solution,part of the reaction is $Na^{+} + e^- \to Na$. This is termed as

$KOOC-CH_2-CH_2-COOK \xrightarrow{\text{electrolysis}} (A) (\text{major})$. Product $(A)$ is:

Identify True $(T)$ or False $(F)$ for the following statements :
$(i)$ In electrolytes,current flows due to electron displacement.
$(ii)$ When current flows from metal,the composition of the metal changes.
$(iii)$ Due to the passage of $DC$ current through the electrolytic solution,a reaction occurs.

Which of the following reactions takes place at the anode during the electrolysis of molten $NaCl$?
