Two solid cylindrical objects X and Y are held fully submerged in a liquid, as shown. The objects have the same volume. The density of the material of Y is twice the density of the material of X. Both objects are stationary. Which statement is correct?

1. AThe force due to the liquid acting on the top surface of X is greater than that acting on the top surface of Y.
2. BThe pressure difference due to the liquid between the top and bottom surfaces of X is the same as that for Y.
3. CThe upthrust acting on X is the same as the upthrust acting on Y.
4. DThe weight of X is the same as the weight of Y.
