Answer
All three containers and contents have the same weight.
Work Step by Step
In container b and container c, the toy displaces its weight in water. If the toy were removed, the water level would drop below the top of the container. However, if we then replaced an amount of water into the container equal to the weight of the toy, the water level would be right at the top, just like container a.
Therefore, all three containers and contents have the same weight.
