Final answer:

The naming of ionic compounds involves naming the cation first, followed by the anion with the suffix -ide; using Roman numerals for transition metal charges; and not changing polyatomic ion names within the compound. Hence, all the listed options are correct.

Step-by-step explanation:

To name ionic compounds, follow these conventions:

  • Name the cation, which is typically a metal or a positively charged polyatomic ion.
  • Then name the anion, which is usually a nonmetal or a polyatomic ion with its ending changed to -ide.
  • If dealing with a transition metal that can have multiple charges, include a Roman numeral in parentheses after the metal's name to indicate its charge (e.g., iron (III) chloride).
  • For polyatomic ions, maintain the name as it is known (e.g., sulfate remains sulfate in a compound).

Therefore, the answer is D) All of the above, as all listed options collectively describe the process of naming ionic compounds.
