Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by
[tex]F_b=\rho _f\times V\times g[/tex]
where [tex]\rho _f[/tex]=density of fluid
V=volume of object under water
g=acceleration due to gravity
