An aluminium sphere is dipped into water. Which of the following is true?

Buoyancy will be less in water at $$0^{\circ} \mathrm{C}$$ than that is water at $$4^{\circ} \mathrm{C}$$

Buoyancy will be more in water at $$0^{\circ} \mathrm{C}$$ than that in water at $$4^{\circ} \mathrm{C}$$

Buoyancy in water at $$0^{\circ} \mathrm{C}$$ will be same as that in water at $$4^{\circ} \mathrm{C}$$

Buoyancy may be more or less in water $$4^{\circ} \mathrm{C}$$ depending on the radius of the sphere
