Answer:
The correct answer is option D.
Step-by-step explanation:
Pressure in defined as force applied per unit area.

Where :
F = Force applied
A = area on which force is applied
We have force applied by the water on bottom of container = F = 450 N
Area of the bottom of the container = A =

Pressure on the bottom of the container:

(1 pa = 0.001 kPa)
0.225 kPa is the water pressure at the bottom of the container.
