Answer:
(a.) If its lid is closed, the water will have no way to get out of the tanker. So, it will put pressure on the sides of the tanker which may lead to its overturning.
(b.) The water will move in the direction in which the truck was formerly moving. This will happen because of inertia and Newton's 1st law.
(c.) Abhishek is very thoughtful as he stopped this dangerous activity which may have lead to loss of water and lives.
(d.) SI unit of average speed is m/s (meters per second).
