Solution

The correct option is C
$P = Q$

$P =$ Weight of an object , $Q =$ Buoyant force or upthrust
Condition given: They are floating in liquid means $P = Q$ .
When body freely floats in a liquid then the weight of whole body is equal to the weight of fluid displaced by the immersed part of body. This is called law of floatation.
Hence, the correct answer is option (C) i.e. $P = Q$
