How many s orbitals are filled in Zr?

I have been going back and forth with this for awhile now. Is it five (s & p)? Or is it 10? I am thinking that it is 10 because they are asking for orbitals (two in each s sublevel).

    The s "sub-level" is one orbital

    The p "sub-level" has three orbitals

    The d "sub-level" has five orbitals

    The f "sub-level" has seven orbitals

    Each orbital can hold a maximum of two electrons

    Zr has five filled s orbitals
