1)Compound C is Ethanoic acid[Acetic acid]
It reacts with sodium metal to form a compound called R . R is Sodium Ethanoate.
2CH3COOH  +2 Na--------------> 2CH3COONa+H2

                                               conc, H2SO4
2) CH3COOH  +C2H5OH       ------ -------------> CH3COOC2H5 + H20
so compound S is Ester or Ethyl ethanoate and compound A is Ethanol
3)CH3COOC2H5+NaoH--------> CH3COONa    + C2H5OH.
so compound R is again Sodium Ethanoate.
So compound C is Ethanoic acid
A is Ethanol
S is Ester
R is sodium Ethanoate.
