Solution

The correct option is D linear with different slopes
For a constant volume process, the P-T curve is always a straight line following the ideal gas law. However, since the vessels have different volumes, the slopes of the lines will be different, with smaller slope for the larger vessel

Two vessels have the same base area but different shapes. The first vessel takes twice the volume of water that the second vessel requires to fill upto a particular common height. Is the force exerted by the water on the base of the vessel the same in the two cases? If so, why do the vessels filled with water to that same height give different readings on a weighing scale?
