1.first process is isothermal.
so,in isothermal process P is proportional to 1/v.so,graph between P. and V is hyperbolic.
so,in both graph B and D it is correctly represented..

2. in second it is said that volume is decreased at constant pressure so,now u can see that only in graph D ,pressure is constant in second process..

so,only option D accurately explain the given process in graphical form..
