Answer:- D) Potassium cyanide.
Explanations:- For naming ionic compounds, first we write the name of the positive ion and then the name of the negative ion. [tex]CN^-[/tex] is a polyatomic ion even then it behaves as a monoatomic anion. Compounds containing this type of ions are called pseudo binary ionic compounds and suffix -de is used for these. [tex]CN^-[/tex] is also written as cyanide.
In KCN, the metal ion is K and it is potassium. The name for the compound KCN is written as potassium cyanide.
