“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.
French etiquette simply would advise you not to answer.
What kind of book did you write after turning 55?
“Il n’y a pas de quoi” . It is friendly and can be slightly familiar but it’s informal and acceptable.
“c’est un plaisir” or “avec plaisir” “c’est mon plaisir” is polite.
If you want to answer to a person saying “merci” you can say also:

“ je t’en prie/ je vous en prie” .It is polite.
