How do you say "you're welcome" in French?

Search: you're welcome in french

Why: While decorating for the Christmas party, which is apparently Hawaiian themed, David found the tape.

• De rien (literally, “it’s nothing") - most common, if talking to a friend
  
• Je vous en prie - more formal, the most polite
• Il n’y a pas de quoi - super casual, like "no problem"
