preposition question

[sallie]

Hi Teachers,

Which preposition should be used in the following sentence? "From" or "of" ?

"This item must not be taken out without the approval __ the manager."


Thank you for your help!

This item must not be taken out without the approval of the manager.

But also:

This item must not be taken out without approval from the manager.

You usually get approval of something and approval for something from someone.

My pick: approval from the manager.
