Explanation:

In the compound $Sr(CN)_2$, $Sr$ is the strontium element. The anion is $CN^-$ which is called cyanide. For ionic compounds, the name starts with the metal cation (strontium) followed by the anion (cyanide). Strontium is an alkaline - earth metal and has a fixed charge of +2 in its compounds, so we don't need to use a Roman numeral to indicate its oxidation state.

Answer:

A. strontium, E. cyanide
