A. is a hypothesis because hypotheses are usually in the form of if-then statements.
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.
For adiabatic process,
PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.
where gamma = Cp
------
Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.
Value of Gamma will be given in question.
Hope this helps!

holacomo es tu pregunta nola entiendo
lanation:
It is the 3rd option. Theories must be substantiated by a large amount of evidence and previous research
