If the immersed body is made in two parts having different densities, then how can it possible?.

Ashutosh said: (Jul 19, 2016)  
Possible only for completely submerged body and of uniform density.

Akash said: (Sep 1, 2016)  

The centre of buoyancy is centre of displaced volume of liquid.

Incorrect is the correct answer for this question.

Nisad said: (Jun 13, 2017)  
Answer should be incorrect.

Please explain it in clear.

Mehul said: (Sep 24, 2017)  

Because buoyancy is not a center of the area but CG is the centre of the area.

Subhasis Roy said: (Oct 12, 2017)  

Because It should only be center of submerged area of rectangle & Circular. NOT FOR ALL.

Buoyancy is not a center of the area but CG of the submerged area.

The Right answer is B.

Rahulda said: (Feb 25, 2018)  
Center of gravity of the displaced volume should be the answer.

Vikash said: (Jul 21, 2018)  
Incorrect is right answer because it is submerged body.

Aniruddh said: (Sep 6, 2018)  
B should be the answer as centre of buoyancy is the centre of displaced liquid.

Vinay said: (Oct 26, 2018)  
Incorrect is the correct answer because the centre of bouncy is the centre of displaced water by the body.

Salahuddin said: (Mar 27, 2019)  
A is the correct answer. Here, It's an immersed body. For an immersed body, COB is the centre of the area of the body itself.

Narendra said: (Dec 19, 2019)  
The stability of an immersed body depends on the respective positions of the center of buoyancy (i.e., the centroid of the displaced volume) and the center of gravity, which do not always coincide. - An immersed body is stable if its center of gravity is aligned below the center of buoyancy (bottom-heavy body).

Amir Hussain said: (Jan 22, 2020)  
Given answer is 100% correct because he is talking about center of area not about center of gravity, and we know that the center of the area doesn't depend on the material of the body.
