Choose the correct statements from the following :  

Option(A) is given that when ${\text{W}}_{\text{B}}\ge {\text{W}}_l$  displaced then body will sink.

But when ${\text{W}}_{\text{B}}\text{=}{\text{W}}_l$  displaced

We get body is suspended by completely immersing in liquid

It will only sink if ${\text{W}}_{\text{B}}\text{>}{\text{W}}_l$  displaced.

Option(B) is given that when ${\text{W}}_{\text{B}}\le {\text{W}}_l$  displaced then the body will float.

But when ${\text{W}}_{\text{B}}\text{=}{\text{W}}_l$  displaced the body will be suspended by completely immersing in the liquid.

It will float when ${\text{W}}_{\text{B}}<{\text{W}}_l$  displaced.

Option(C) when a body floats in a liquid the portion of the body present above the surface of liquid is independent of relative density of body with liquid.

But the portion remain above the surface certainly depend on the density of body relative to liquid.

Option(D) Hydrogen balloon rises up still air up to certain height only. Obviously true because the hydrogen balloon rise up until upthrust generated is equal to its weight and remain suspended at a particular height in still air.
