Solution
The correct option is B Vertically down
Buoys are made of materials which are less dense than water, therefore they stay afloat.
When completely submerged in water, the net buoyant force will be greater than its weight and a net upward force will act on it. Therefore, in order to counterbalance this upward force, the tension in the thread should act in a vertically downward direction.
