Answer

Correct option: A.
$(i) B (ii) D$
a
(a)Due to acceleration towards right, there will be a pseudo force in a left direction. So the pressure will be more on rear side (Points $A $ and $B$) in comparison with front side (Point $D$ and $C$).
Also due to height of liquid column pressure will be more at the bottom (points $ B $ and $C$) in comparison with top (point $A$ and $D$).
So overall maximum pressure will be at point $B $ and minimum pressure will be at point $D$.
