A man is carrying a bucket with water. If a object is kept in it which floats in water, man will feel
I think when the body floats its weight is balanced by upthrust so no further be felt. Is it right or wrong?

The man will have to carry the extra weight.
The object floats on the water, because the forces on it balance out. Gravity pulls the object down, the water pushes it up.
Now hold part of that thought:
Thus the bucket and its content are heavier when you add extra stuff to it. (Even if it floats).
Not using answer
The answer is 1.
The total weight of is that of the man, the bucket, the water and the wood. The fact that the wood displaces more water than its own weight does not change its weight. That just explains why it floats.
Try it yourself. Stand on scales with a bucket of water, then lift a block of wood and see the weight change. Finally, put the wood in the water and ther will be no further change at all.
