Why $NH_3$ cannot be dried by $H_2SO_4$,$P_2O_5$,and $CaCl_2$?

• A
  Because $NH_3$ does not react with $H_2SO_4$,$P_2O_5$,and $CaCl_2$.
• B
  Because $NH_3$ does not react with water.
• C
  Because $NH_3$ does not react with $C_6H_6$.
• D
  Because $NH_3$ reacts with $H_2SO_4$,$P_2O_5$,and $CaCl_2$.
