Impedance Diagram of Low Pass Filter

A proper answer requires more information about the filter than "low
pass". For one thing, phase is a relative measure. You must describe
what your reference is and where you want the angle. A drawing would help.

Presuming a RC ladder section
Item 1 is correct if you drop i in w; so w=2*pi*f
I presume that this is homework.  You need to walk through the formulas
and diagrams.  This answer is right for this case, but the problem will
occur again and you need to understand the fundamentals.
Consider the divider formula Xc/(Xc+R)  then 1/(1+R/Xc)
compute the phase angle.
Then draw the complex plane figures and see how you get the same
answer.
At some point the "meaning" will come through.
It's there just look a little.
