Answer

Answer:

D. potassium cyanide

Brief Explanations:

KCN consists of the potassium cation ($\text{K}^+$) and the polyatomic cyanide anion ($\text{CN}^-$). The standard chemical name for this ionic compound is potassium cyanide, which matches option D. The other options incorrectly name the polyatomic ion or use non-standard naming conventions for this compound.
