The correct meaning of the word "coup de grâce" is:  the final blow

Coup de grâce  is a French term literally translating to "blow of mercy."
It refers to the final blow that finishes someone or something off, often used figuratively for a decisive act that brings something to an end.

 The other options are not as accurate:
