(D) The reaction $HgS + HNO_3 \text{ (Conc.)} \longrightarrow \text{No reaction}$ indicates that $HgS$ (mercuric sulfide) is highly insoluble in concentrated nitric acid due to its extremely low solubility product constant $(K_{sp})$. Since no dissolution occurs,this corresponds to the category of 'No reaction'.
