P=pgh, remeber that g=9.8 , so ignoring the atmosheric pressure you would just multiply 9.8x4 and you would get 39.2KPa

Answer

C.39.2 kPa


Explanation

The pressure in liquids depend on the depth or what we call the liquid column(h), the density of the liquid(σ) and the the acceleration due to gravity(g).

h = 4.00 m

σ = 1000 Kg/m³

g = 9.8m/s²


Pressure Is given by;

P = σgh

= 1000 × 9.8 × 4

= 39200 Pa

=39.2 KPa
