Questions true or false

Hello, I have some questions to say true or false.
a) In a P,T,V system always will be true ;
integrate(P dv)greater than or equal (W out)
if the system has friction.
b)In Thermodynamic the work who cross system border is always process function
c)The adiabatic work in Thermodynamic who cross the border in a closed system is independent of process and depends of the final and initial status
d)In a Expansion no reverse it`s true ;W(expansion)=W(useful)+W(friction)+W(atmospheric)

3. The attempt at a solution
Well I think a) and c) are true and b) d) are false

Thank you
