We know that, the centre of pressure for a plane uniform vertical surface lies at the depth of two-thirds of the height of immersed portion.
So, here we get 2/3 of 3m which is equal to 2m.
The given answer is correct.

The center of pressure is located at the centroid of the rectangular shaped pressure field 2/3 from the top of the water line.
b = 4 m, d = 3 m.
Center of pressure = 2/3 d = (2/3)*3 = 2.0 m.
b = 4 m, d = 3 m.
Center of pressure = 2/3 d = (2/3)*3 = 2.0 m.

Center of pressure is always below the centre of gravity and CG is located at point H/2 = 1.5m so simply we can make an idea that it will be at 2m.

CP = (Ig/Ax)+x.
CP = ((bd3/12)/bd*d/2)+1.5,
CP = (d/6)+1.5,
CP = 1/2+1.5,
CP = 2.
C is the right one.
CP = ((bd3/12)/bd*d/2)+1.5,
CP = (d/6)+1.5,
CP = 1/2+1.5,
CP = 2.
C is the right one.

CG equals CP when water surface coincides the body surface. Therefore cg=cp=3/2=1.5.
Am I right?

@All.
It's very simple
Gate is vertical.
Means H = 4m.
D/2 = 4/2 = 2.

Area = b*d.
CG (y)= d/2.
Ig = bd3/12.
Center of pressure = y + Ig/Ay.
CG (y)= d/2.
Ig = bd3/12.
Center of pressure = y + Ig/Ay.

2/3 height if water is full, if not full then it's 5 of water.

Depth of center of gravity,
H = 2h/3
= 2*3 / 3
= 2 m.
H = 2h/3
= 2*3 / 3
= 2 m.

The depth of the center of pressure= 2H/3.
(2*3)/3 =2m.
(2*3)/3 =2m.
