143357 A piece of ice is tied using a string to the bottom of bucket $A$. The bucket is filled with water with ice completely submerged in it.
Another bucket $B$ is filled with water and a piece of ice is released in water. It floats on the surface of water (see fig.). What would be the impact on the level of water in the two buckets when ice pieces melt away completely?

1 Level of water remain unchanged in both the buckets
2 Level of water will go down in bucket A but will remain unchanged in bucket $B$
3 Level of water will go down in bucket A but will go up in bucket $\mathrm{B}$
4 Level of water will remain unchanged in bucket A but will go up in bucket B
