A cyclic process is shown in the p-T diagram where line AB is passing through the origin. Which of the curves show the same process on a V-T diagram?

We wish to convert P-T graph to V-T graphProcess A to B is isochoric process in which temperature increaes.Process B-C is isothermal process in which pressure decreases means volume increases.Hence B-C is isothermal expansion.Process C to A is isobaric process in which temperature decrease.hence volume decreases.So C to A is isobaric compression.
