Formally put an end to a system, practice, or institution

Abolish

The correct option is abolish. It means "to formally put an end to something, especially a system, practice, or institution." The other options are not correct substitutes.

• Stop means to bring something to an end, but it does not necessarily mean to do so formally.
• Destroy means to completely ruin or put an end to something, but it is often used in a more violent or destructive sense than abolish.
• Kill means to cause the death of someone or something, which is a much more extreme action than abolish.
