Janice mixed in orange solution of sodium sulfide with a clear solution of hydrochloride acid. she noticed after a minute that the solution smelled something like a rotten eggs. what could she reasonably infer from the order released by the solution

That the hydrochloric acid reacted with the sodium sulfide to produce the same gas that is formed from rotten eggs.  

Explanation:

The equation for the reaction for the reaction is

     Na₂S(aq)     +       2HCl(aq)         ⟶    2NaCl(aq)     +          H₂S(g)

sodium sulfide + hydrochloric acid ⟶ sodium chloride + hydrogen sulfide

i think it's c. i'm not sure but i think so.
