The given graph represents the variation of \( \mathrm{Z} \) (compressibility factor \( =\frac{\mathrm{PV}}{n \mathrm{RT}} \) ) versus \( \mathrm{P} \), for three real gases A, B and C. Identify only the incorrect statement.
(A) For the gas A, \( a=0 \) and its dependence on \( \mathrm{P} \) is linear at all pressure.
- (B) For the gas \( \mathrm{B}, b=0 \) and its dependence on \( \mathrm{P} \) is linear at all pressure.
(C) For the gas \( \mathrm{C} \), which is typical real gas for which neither \( a \) nor \( b=0 \). By knowing the minima and the point of intersection, with \( \mathrm{Z}=1, a \) and \( b \) can be calculated.
(D) At high pressure, the slope is positive for all real gases.
