Answer:

H_3O^+ + Cl^- is present in a "dilute aqueous solution of hydrochloric acid (HCl).  

Option (a).

Explanation:

HCl is a very strong acid, strong acids in the aqueous solution ionizes to large extent hence producing the large amount of hydrogen ions. Its pH is around 3.

It is a colorless and transparent liquid. The produced hydrogen combines with the molecules of the hydrogen to give hydronium atoms. On the other hands the "weak acids ionize partially", they contain ions as well the molecules.
