Solution

The correct option is D C
The upthrust on the body by each liquid is same and it is equal to the weight of body. But upthrust=volume submerged $\times ρ_{l} \times g$ . For liquid C, since volume submerged is least so denisty $ρ_{3}$ must be maximum.

The correct option is D CThe upthrust on the body by each liquid is same and it is equal to the weight of body. But upthrust=volume submerged×ρl×g. For liquid C, since volume submerged is least so denisty ρ3 must be maximum.
