Figures (a) and (b) refer to the steady flow of a (non-viscous) liquid. Which of the two figures is incorrect ? Why?

Figures (a) and (b) refer to the steady flow of a (non-viscous) liquid. Which of the two figures is incorrect ? Why ?

Figure (a) is incorrect. According to the equation of continuity a V = constant, where area of flow is more. So, the velocity of liquid flow at a constriction of tube is more than other portion.
