Concept:A body sinks when its density is greater than the density of the fluid it is in.
Explanation:The sinking or floating depends on the relative densities of the body and water.
If the body’s density is more than water’s density, the buoyant force is smaller than the weight.
Thus, the condition to sink is:
ρbody>ρwater.
This is equivalent to: density of water < density of body.
If densities are equal, the body remains suspended.
If body density is less, it floats.
Hence, the correct option matches the condition where water’s density is less than the body’s density.
Answer:Option B: density of water is less than density of body.
