Answer

Brief Explanations:

Strong electrolytes dissociate completely in solution. $NaNO_3$ is a soluble salt, $NaOH$ is a strong base, $Ca(OH)_2$ is a strong base (although slightly soluble), and $HI$ is a strong acid. $NH_3$ is a weak base and only partially ionizes in water, making it a weak electrolyte.

Answer:

C. $NH_3$
