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

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.

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.

@Aadarsh.
4m isn't height its width of gate H = 3m.
4m isn't height its width of gate H = 3m.

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.

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