The answer is D. NH4NO3.
This is because:
* Ammonium nitrate (NH4NO3), when heated, decomposes to produce dinitrogen (I) oxide (N2O) and water (H2O). This is a specific and well-known chemical reaction.
Here's the chemical equation:
* NH4NO3 (heat) β N2O + 2H2O
The other options decompose in different ways:
* Sodium nitrate (NaNO3) decomposes to sodium nitrite and oxygen.
* Zinc nitrate (Zn(NO3)2) and copper nitrate (Cu(NO3)2) decompose to their respective metal oxides, nitrogen dioxide, and oxygen.

Ans is D
Nh4no3.......n2o + 2h2o
It decomposes to give dinitrogen 1 oxide and water
