Ethylene is produced when
a. Ethanol reacts with ethanoic acid in presence of a few drops of conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \)
b. Ethanol is oxidised with acidified \( \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \)
c. Ethanol is heated with excess of conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at \( 443 \mathrm{~K} \)
d. Ethanoic acid reacts with sodium carboante
