“Il n’y a pas de quoi” . It is friendly and can be slightly familiar but it’s informal and acceptable.
“ je t’en prie/ je vous en prie” .It is polite.
If you want to answer to a person saying “merci” you can say also:
“c’est un plaisir” or “avec plaisir” “c’est mon plaisir” is polite.
“De rien” is not correct although it is often heard. Avoid it. It should be “Ce n’est rien”.
“Pas de problème” is common and sounds uneducated. It’s often used though.
