Answer: Option B
Explanation: First, density is defined as mass/volume, so for two objects with the same volume, the more dense one has more weight.
Here we see that the apple is less dense than the water, which means that the water is heavier than the apple.
This means that only a tiny part of the apple will be submerged in the water (where the displaced water/profundity of the apple depends on the size of the apple, the displaced water must have the same weight than the apple, in that point the forces are canceled a the apple will be at rest)
The correct option is B
