Answer: The correct answer is NH_3

Explanation:

Nessler's reagent is an alkaline solution of potassium tetraiodomercurate (II). When this reagent is added to the water extract of an unknown solution, a brown precipitate of basic amidoiodomercury (II) is formed if ammonium ions are one of the constituents of the substance.

Hence, only NH_3 will give a test with nessler's reagent.

The equations for the above test is provided in the image below.
