A plot of volume (V) versus temperature (T) for a gas at constant pressure is a straight line passing through the origin . The plots at different values of pressure are shown in figure .
Which of the following order of pressure is correct for this gas ?
A. `P_(1)gt P_(2)gt P_(3)gt P_(4)`
B. `P_(1)=P_(2)P_(2)=P_(3)=P_(4)`
C. `P_(1)lt P_(2)lt P_(3)lt P_(4)`
D. `P_(1)lt P_(2)=P_(3)lt P_(4)`
